Although the most promising applications of ionogels require their contact with aqueous media, few data are available on the stability of ionogels upon exposure to water. In this paper, a simple, easy-to-setup and precise method is presented, which was developed based on the continuous conductivity measurements of an aqueous phase, to study the washout of imidazolium ionic liquids (IL) from various silica-based ionogels immersed in water. The accuracy of the method was verified using HPLC, its reproducibility was confirmed, and its systematic errors were estimated. The experimental data show the rapid and almost complete (>90% in 5 h) washout of the hydrophilic IL (1-butyl-3-methylimidazolium dicyanamide) from the TMOS-derived silica ionogel. To lower the rate and degree of washout, several approaches were analysed, including decreasing IL content in ionogels, using ionogels in a monolithic form instead of a powder, constructing ionogels by gelation of silica in an ionic liquid, ageing ionogels after sol–gel synthesis and constructing ionogels from both hydrophobic IL and hydrophobic silica. All these approaches inhibited IL washout; the lowest level of washout achieved was ~14% in 24 h. Insights into the ionogels’ structure and composition, using complementary methods (XRD, TGA, FTIR, SEM, NMR and nitrogen adsorption), revealed the washout mechanism, which was shown to be governed by three main processes: the diffusion of (1) IL and (2) water, and (3) IL dissolution in water. Washout was shown to follow pseudo-second-order kinetics, with the kinetic constants being in the range of 0.007–0.154 mol−1·s−1.

A synthetic approach to production of monolithic (NH4)3H(Ge7O16)(H2O)x and (NH4)2Ge7O15 aerogels is developed. Production of the aerogels with the germanate zeolite-like structure is reported for the first time. Thermal decomposition of (NH4)2Ge7O15 leads to formation of GeO2 aerogel, which has been obtained before using much more complex and expensive process of alkoxide hydrolysis. The suggested synthetic route might be used for production of novel luminescent, catalytic and anode materials. Luminescent properties of all obtained aerogels revealed excitation dependence. Based on excitation wavelengths it could exhibit blue, yellow-green and red luminescence. Luminescent properties for (NH4)3H(Ge7O16) (H2O)x and (NH4)2Ge7O15 are reported for the first time.

An ever-increasing number of applications of oxide aerogels places a high demand on wettability-tuning techniques. This work explores the possibility to cheaply prepare GeO2 aerogels with controlled wettability by an ambient pressure drying (APD) method. GeO2 aerogels are prepared via two synthetic routes. Surface modification is carried out by soaking the gels in a silylating agent solution; type and concentration of the modifier are optimized to achieve a large surface area. The aerogels have been characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, nitrogen adsorption and contact angle measurements. The effect of surface modification on the phase composition and particle size of the aerogels is described. In summary, the work provides a new cheap production method for the preparation of both hydrophobic and hydrophilic GeO2 aerogels with contact angle varying from 30° to 141° and with surface area of 90–140 m2/g, which facilitates the expansion of their diverse applications. GeO2 aerogel synthesis by APD is reported for the first time.

A series of silica-based aerogels comprising novel bifunctional chelating ligands was prepared. To produce target aerogels, two aminosilanes, namely (3-aminopropyl)trimethoxysilane (APTMS) and N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (AEAPTMS), were acylated by natural amino acids ((S)-(+)-2-phenylglycine or L-phenylalanine), followed by gelation and supercritical drying (SCD). Lithium tetrachloropalladate was used as the metal ion source to prepare strong complexes of Pd2+ with amino acids covalently bonded to a silica matrix. Aerogels bearing chelate complexes retain the Pd2+ oxidation state after supercritical drying in CO2, but the Pd ion is reduced to Pd metal after SCD in isopropanol. Depending on the structure of amino complexes, Pd-containing aerogels showed catalytic activity and selectivity in the hydrogenation reactions of C=C, C≡C and C=O bonds.

The immobilisation of ionic liquids (ILs) in porous solid matrices enables the design of ionogels, which are now regarded as a promising material in extraction science. Here, by the co-gelation of TMOS and MTMS in a commercially available ionic liquid, Aliquat 336 (A336Cl), a series of ionogels were synthesised with various levels of IL content and matrix hydrophobicity. Both of these factors were shown to have a small effect on Fe(III) extraction efficiency (57–70 %), while they strongly influenced the re-extraction efficiency (15–45 %) of the materials. The ionogels with the highest IL content (80 %) and a highly hydrophilic silica matrix showed the best extraction and re-extraction performance. A thorough characterisation of the ionogels confirmed the confinement of the IL in silica and revealed Fe(III) extraction mechanisms. It was shown that iron was extracted from the aqueous solutions by A336Cl@SiO2 ionogels in the form of FeCl4– ions typical of the extraction by pure A336Cl. Unexpectedly, the iron extraction by the ionogels resulted in the formation of Fe2Cl7– species that had not been observed earlier in the A336Cl-based extraction systems. Moreover, iron(III) directly bound to hydrophilic silica through Si–O–Fe bridges, and it was also found that, in the ionogels, the admixtures of alcohols could even reduce ferric ions to ferrous species. For the ionogels, both iron extraction and re-extraction followed pseudo-second order kinetics. Iron re-extraction from the ionogels with aqueous sulfuric acid solution resulted in the loss of recyclability, most probably due to the formation of FeSO4⋅H2O in the ionogels. The cycling performance of the ionogels can be improved by their conditioning in chloride-rich media after re-extraction stages.

The behavior of cerium tetrafluoride hydrate was studied in water at a temperature of 80°C and under hydrothermal treatment at 100, 130, and 220°C for a day. The product of the hydrothermal treatment of CeF4·H2O at 100°C was investigated by chemical, thermogravimetric, IR spectroscopic, and X-ray powder diffraction analyses, which identified a new cerium fluoride with the composition, presumably, Ce3F10⋅3H2O or, most likely, (H3O)Ce3F10⋅2H2O. New compound crystallizes in the space group $$Fm\bar {3}m$$ with a unit cell parameter of 11.66 Å. Hydrothermal treatment of cerium tetrafluoride hydrate at temperatures above 130°C leads to hydrolysis and reduction of cerium(IV) fluoride compounds to form CeO2 and CeF3.

In a new series of LnIII–CrIII cyclopropane-1,1-dicarboxylates, a decrease in the Ln3+ ionic radius leads to a change in a space group and the transition of a 3D framework structure (Ln = Eu, Gd, Tb) into a 2D layered one (Ln = Dy, Ho, Y, Er, Yb).

The structure and hardness of an aluminum-matrix Al–Si–Cu-based material reinforced with WO3 nanoparticles via liquid phase mixing with a melt according to two versions, namely, using a mixture of WO3 with a copper powder and without it, are studied. The existence of transport effect of a copper powder, which ensures a uniform distribution of WO3 nanoparticles in the composite volume, is confirmed. The most homogeneous structure and a high hardness of the composite material are reached in the case of introduction of a mixture of 1 wt % WO3 and Cu powder taken at a weight ratio of 1 : 3.

Aerogels containing rare earth elements are promising compounds for designing various functional materials, since they combine the properties of aerogels - high surface area and porosity, and the luminescent and catalytic properties of rare earth elements. A modified sol-gel method was developed to produce mixed rare earth oxide aerogels (Eu2O3/Gd2O3, Eu2O3/Yb2O3, and Gd2O3/Yb2O3) with high metal to metal molar ratio (1:1) and individual (Eu2O3, Gd2O3, and Yb2O3) aerogels. Rare earth nitrates, propylene oxide, and citric acid were used for the synthesis of monolithic halogen-free rare earth oxide aerogels. The aerogels obtained by supercritical drying in CO2 possess mesoporous structure and high surface area (180–350 m2/g). Uniform distribution of elements in binary oxides was confirmed by EDX. Calcination at 600–800 °С causes crystallization of the amorphous aerogels. XRD patterns of the binary oxides after calcination corresponded to single phase cubic ( $$Ia\overline 3$$ ) structure of rare earth M2O3 oxide, which indicated the formation of solid solutions. The Eu2O3/Gd2O3 and Eu2O3 aerogels demonstrate strong luminescence in visible region at near UV excitation, which was also observed after calcination of the aerogels at 800 °C.

The enzyme-like activity of metal oxide nanoparticles is governed by a number of factors, including their size, shape, surface chemistry and substrate affinity. For CeO2 nanoparticles, one of the most prominent inorganic nanozymes that have diverse enzymatic activities, the size effect remains poorly understood. The low-temperature hydrothermal treatment of ceric ammonium nitrate aqueous solutions made it possible to obtain CeO2 aqueous sols with different particle sizes (2.5, 2.8, 3.9 and 5.1 nm). The peroxidase-like activity of ceria nanoparticles was assessed using the chemiluminescent method in different biologically relevant buffer solutions with an identical pH value (phosphate buffer and Tris-HCl buffer, pH of 7.4). In the phosphate buffer, doubling CeO2 nanoparticles’ size resulted in a two-fold increase in their peroxidase-like activity. The opposite effect was observed for the enzymatic activity of CeO2 nanoparticles in the phosphate-free Tris-HCl buffer. The possible reasons for the differences in CeO2 enzyme-like activity are discussed.

Abstract
This study investigated the characteristics of a nano-web made using the electrospinning technique, which incorporated Halloysite clay nanotubes. The focus was on understanding how different ultrasonic frequencies affected the properties of the nano-web. Through the use of field emission scanning electron microscopy and elemental mapping, it was confirmed that the Halloysite clay nanotubes were present and provided insights into the morphology of the samples. The electrical conductivity results were impressive, and the treated specimens showed higher crease recovery properties compared to the untreated ones, thanks to the presence of Halloysite clay nanotubes and the various ultrasound frequencies used. In addition, the samples demonstrated improved ultraviolet-blocking abilities as well as excellent strength and resistance to abrasion. Overall, the nanocomposite webs displayed promising features that could find applications in multiple industries.

Methyl mercaptan is a sulfur-based chemical found as a co-product in produced natural gas and it causes corrosion in pipelines, storage tanks, catalysts, and solid adsorption beds. To improve the quality of methane produced, researchers have studied the use of metal oxides and aluminum silicates as catalysts for removing mercaptan. However, there are restrictive limitations on the efficiency of metal oxides or aluminum silicates as adsorbents for this application. Therefore, this study investigated the performance of these materials in a fixed-bed reactor with simulated natural gas streams under various operating conditions. The testing procedure includes a detailed assessment of the adsorbent/catalysts by several techniques, such as Braeuer–Emmett–Teller (BET), Scanning Electron Microscope (SEM), Energy-Dispersive X-ray Spectrometry (EDS), and X-ray Photoelectron Spectroscopy. The results revealed that metal oxides such as copper, manganese, and zinc performed well in methyl mercaptan elimination. The addition of manganese, copper, and zinc oxides to the aluminum silicate surface resulted in a sulfur capacity of 1226 mg S/g of catalyst. These findings provide critical insights for the development of catalysts that combine metal oxides to increase adsorption while reducing the production of byproducts like dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) during methyl mercaptan removal.

New composite materials (ionogels) have been obtained based on imidazolium ionic liquids immobilized in highly porous polymers, i.e., polyamide 6,6 (nylon 6,6) and low-density polyethylene. A method has been proposed for determining the rate of ionic liquid removal from an ionogel upon contact with water, with this method being based on continuous measuring the conductivity of an aqueous phase. The results of the conductometric measurements have been confirmed by high-performance liquid chromatography data. It has been shown that the stability of ionogels upon contact with water is determined by both the hydrophobicity of a polymer matrix and the solubility of an ionic liquid in water. The highest degree of ionic liquid removal (more than 80%) has been observed for composites based on porous polyamide 6,6 (hydrophilic matrix) and dicyanimide 1-butyl-3-methylimidazolium (completely miscible with water). Ionogels based on lowdensity polyethylene (hydrophobic matrix) and bis(trifluoromethylsulfonyl)imide 1-butyl-3-methylimidazolium (poorly soluble, 1 wt %, in water) have shown the highest stability (washout degree of no more than 53% over 24 h). The method proposed for analyzing the rate of ionic liquid dissolution in water has been used to discuss the mechanism of this process.

This study compared the chemical, structural, and luminescent properties of xerogel-based ceramic powders (CPs) with those of a new series of crystallized aerogels (CAs) synthesized by the epoxy-assisted sol–gel process. Materials with different proportions of Eu3+ (2, 5, 8, and 10 mol%) were synthesized in Lu2O3 host matrices, as well as a Eu2O3 matrix for comparative purposes. The products were analyzed by infrared spectroscopy (IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy-dispersive spectroscopy (EDS), transmission electron microscopy (TEM), photoluminescence analysis, and by the Brunauer–Emmett–Teller (BET) technique. The results show a band associated with the M-O bond, located at around 575 cm−1. XRD enabled us to check two ensembles: matrices (Lu2O3 or Eu2O3) and doping (Lu2O3:Eu3+) with appropriate chemical compositions featuring C-type crystal structures and intense reflections by the (222) plane, with an interplanar distance of around 0.3 nm. Also, the porous morphology presented by the materials consisted of interconnected particles that formed three-dimensional networks. Finally, emission bands due to the energy transitions (5DJ, where J = 0, 1, 2, and 3) were caused by the Eu3+ ions. The samples doped at 10 mol% showed orange-pink photoluminescence and had the longest disintegration times and greatest quantum yields with respect to the crystallized Eu2O3 aerogel.

New coordination polymers were synthesized. A ditopic centrosymmetric organic ligand containing oxazole heterocycles, 4,8-dichlorobenzo[1,2d:4,5d´]bis(oxazole)-2,6(3H,7H)-dithione (H2L), was prepared and structurally characterized. It was shown that deprotonated H2L forms non-luminescent binuclear molecular complexes Li2L(THF)6 (I) and Na2L(DME)4 (II) with alkali metals, while complexes of H2L with lanthanides are ionic compounds [Ln(DMSO)8][L]1.5 (Ln = Nd (III), Yb (IV)) exhibiting moderate metalcentered emission in the near-infrared (IR) range, despite the absence of coordination of the ligand L to lanthanide ions. The molecular structures of H2L·2DMSO and I–III were established by X-ray diffraction (CCDC no. 2320461 (H2L·2DMSO), 2320462 (I), 2320463 (II), 2320464 (III)).

In this study, we developed a wearable nanozyme–enzyme electrochemical biosensor that enablies sweat lactate monitoring. The biosensor comprises a flexible electrode system prepared on a polyimide (PI) film and the Janus textile for unidirectional sweat transport. We obtained favorable electrochemical activities for hydrogen peroxide reduction by modifying the laser-scribed graphene (LSG) electrode with cerium dioxide (CeO2)–molybdenum disulphide (MoS2) nanozyme and gold nanoparticles (AuNPs). By further immobilisation of lactate oxidase (LOx), the proposed biosensor achieves chronoamperometric lactate detection in artificial sweat within a range of 0.1–50.0 mM, a high sensitivity of 25.58 μA mM−1cm−2 and a limit of detection (LoD) down to 0.135 mM, which fully meets the requirements of clinical diagnostics. We demonstrated accurate lactate measurements in spiked artificial sweat, which is consistent with standard ELISA results. To monitor the sweat produced by volunteers while exercising, we conducted on-body tests, showcasing the wearable biosensor's ability to provide clinical sweat lactate diagnosis for medical treatment and sports management.

Ionic liquids (ILs) play a crucial role in the design of novel materials. The ionic nature of ILs provides numerous advantages in drug delivery, acting as a green solvent or active ingredient to enhance the solubility, permeability, and binding efficiency of drugs. They could also function as a structuring agent in the development of nano/micro particles for drug delivery, including micelles, vesicles, gels, emulsion, and more. This review summarize the ILs and IL-based gel structures with their advanced drug delivery applications. The first part of review focuses on the role of ILs in drug formulation and the applications of ILs in drug delivery. The second part of review offers a comprehensive overview of recent drug delivery applications of IL-based gel. It aims to offer new perspectives and attract more attention to open up new avenues in the biomedical applications of ILs and IL-based gels.

Two-component ionogels containing clay minerals such as montmorillonite K10 (Mnt-K10), bentonite (Bent), and halloysite (Hly), as well as imidazolium-based ionic liquids (ILs) were prepared in present work. The ILs that were used in the synthesis included a bis(trifluoromethylsulfonyl) imide anion (TFSI-) and various cations: 1-ethyl-3-methylimidazolium (EMIm+), 1-propyl-3-methylimidazolium (PMIm+), 1-butyl-3-methylimidazolium (BMIm+), and 1-butyl-2,3-dimethylimidazolium (BDMIm+). The thermal behavior of the synthesized ionogels and neat ILs was investigated using differential scanning spectroscopy (DSC) and thermogravimetric analysis (TG). It was found that the thermograms of PMImTFSI, BMImTFSI, and BDMImTFSI showed inflections corresponding to glass-transition, which shifted towards higher temperatures with the introduction of aluminosilicate. The largest shifts compared to the neat ILs were observed for IL/Bent ionogels. It was assumed that the identified differences in the thermal behavior between the neat and clay-entrapped ILs (confinement effect) are associated with an increased role of ion-wall interactions compared to ion-ion interactions. When studying the thermal stability of the materials under consideration, two opposite trends were noted. On the one hand, the characteristic temperatures of thermal decomposition of the synthesized ionogels were lower than those for the neat ILs. But on the other hand, when introducing aluminosilicate into any IL, a decrease in the maximum rate of thermal decomposition was observed in accordance with series of IL > IL/Mnt-K10 > IL/Hly > IL/Bent.

Based on the fact that flexible electronic devices have the property of sensing human movement and monitoring physiological signals, this will pave the way for the development of wearable electronic devices that can be stretched. Ionogels have become a focal point in the field of flexible and stretchable wearable electronics by combining carefully selected chemical properties of ionic liquids with superior physicochemical properties. To accommodate with the application environment of flexible electronics, researchers' interest in toughening ionogels continues to increase. Consequently, this review systematically discusses the advancements made in stretchable ionogels from both structural design and toughening mechanism perspectives. Moreover, this review classifies these ionogels for flexible stretchable wearable electronic devices into several key application areas, including ionic skin, human motion detection, human–machine interactions and flexible energy storage devices. Finally, the challenges and prospects of stretchable ionogels are summarized, providing forward-looking strategies for further applications in wearable electronics.

Photoreforming is a clean photocatalytic technology for simultaneous plastic waste degradation and hydrogen fuel production, but there are still limited active and stable catalysts for this process. This work introduces the brookite polymorph of TiO2 as an active photocatalyst for photoreforming with an activity higher than anatase and rutile polymorphs for both hydrogen production and plastic degradation. Commercial brookite successfully converts polyethylene terephthalate (PET) plastic to acetic acid under light. The high activity of brookite is attributed to good charge separation, slow decay and moderate electron trap energy, which lead to a higher generation of hydrogen and hydroxyl radicals and accordingly enhanced photo-oxidation of PET plastic. These results introduce brookite as a stable and active catalyst for the photoconversion of water contaminated with microplastics to value-added organic compounds and hydrogen.

However, the practical application of hydrogel‐based ZABs is limited by their short service life, narrow operating temperature range, and repair difficulty. Herein, a self‐healing ionogel is synthesized by the photopolymerization of acrylamide and poly(ethylene glycol) monomethyl ether acrylate in 1‐ethyl‐3‐methylimidazolium dicyanamide with zinc acetate dihydrate and first used as an electrolyte to fabricate self‐healing ZABs. The obtained self‐healing ionogel has a wide operating temperature range, good environmental and electrochemical stability, high ionic conductivity, satisfactory mechanical strength, repeatable and efficient self‐healing properties enabled by the reversibility of hydrogen bonding, and the ability to inhibit the production of dendrites and by‐products. Notably, the self‐healing ionogel has the highest ionic conductivity and toughness compared to other reported self‐healing ionogels. The prepared self‐healing ionogel is used to assemble self‐healing flexible ZABs with a wide operating temperature range. These ZABs have ultra‐long cycling lives and excellent stability under harsh conditions. After being damaged, the ZABs can repeatedly self‐heal to recover their battery performance, providing a long‐lasting and reliable power supply for wearable devices. This work opens new opportunities for the development of electrolytes for ZABs.

By reacting CeF3 with XeF2 the anhydrous CeF4 was synthesized and studied by XRD, SEM, FTIR, 19F NMR spectrometry and thermogravimetry. It was found that CeF4 undergoes hydration upon keeping in air forming the crystalline hydrate with the approximate formula [CeF4•0.2H2O]*0.7H2O. Water molecules both enter the coordination sphere of cerium and form crystalline hydrates with cerium(IV) fluoride due to OH…F hydrogen bonds in the crystal lattice.

The immobilisation of ionic liquids (ILs) in porous solid matrices enables the design of ionogels, which are now regarded as a promising material in extraction science. Here, by the co-gelation of TMOS and MTMS in a commercially available ionic liquid, Aliquat 336 (A336Cl), a series of ionogels were synthesised with various levels of IL content and matrix hydrophobicity. Both of these factors were shown to have a small effect on Fe(III) extraction efficiency (57–70 %), while they strongly influenced the re-extraction efficiency (15–45 %) of the materials. The ionogels with the highest IL content (80 %) and a highly hydrophilic silica matrix showed the best extraction and re-extraction performance. A thorough characterisation of the ionogels confirmed the confinement of the IL in silica and revealed Fe(III) extraction mechanisms. It was shown that iron was extracted from the aqueous solutions by A336Cl@SiO2 ionogels in the form of FeCl4– ions typical of the extraction by pure A336Cl. Unexpectedly, the iron extraction by the ionogels resulted in the formation of Fe2Cl7– species that had not been observed earlier in the A336Cl-based extraction systems. Moreover, iron(III) directly bound to hydrophilic silica through Si–O–Fe bridges, and it was also found that, in the ionogels, the admixtures of alcohols could even reduce ferric ions to ferrous species. For the ionogels, both iron extraction and re-extraction followed pseudo-second order kinetics. Iron re-extraction from the ionogels with aqueous sulfuric acid solution resulted in the loss of recyclability, most probably due to the formation of FeSO4⋅H2O in the ionogels. The cycling performance of the ionogels can be improved by their conditioning in chloride-rich media after re-extraction stages.

Minimizing energy losses and ensuring smooth motion between engine components is the critical role of lubricants. Extensive research over the past decade has explored various lubricant types and additives. Ionic liquids (ILs) have emerged as promising candidates due to their exceptional tribological performance, which is attributed to their unique physiochemical properties. This review delves into the potential of ILs as both lubricants and additives, focusing on their structure-activity relationship in the quest for identifying green lubricants. Compared to neat base oils, ILs significantly reduce friction and wear. This review explores the role of ILs in water-based lubricants (WBLs) and analyzes the impact of tribo-testing conditions based on different tribometers. A recent trend involves the use of ILs and nanoparticles (NPs) as hybrid lubricant additives. The review examines the synergistic behaviour of these hybrid additives in different base oils and proposes a lubrication mechanism for phosphonium ILs based on tribo-film formation induced by tribo-chemical reactions during the rubbing process. The lubrication mechanism of hybrid nano-lubricants is also comprehensively reviewed to explain why combining NPs and ILs results in such remarkable reductions in friction and wear. Overall, this review provides a comprehensive overview of the promising potential of ILs in lubrication, highlighting their advantages, diverse applications, and underlying mechanisms.

AbstractSilicon and Germanium oxide (SiOx and GeOx) nanostructures are promising materials for energy storage applications due to their potentially high energy density, large lithiation capacity (~10X carbon), low toxicity, low cost, and high thermal stability. This work reports a unique approach to achieving controlled synthesis of SiOx and GeOx nanostructures via photonic curing. Unlike conventional methods like rapid thermal annealing, quenching during pulsed photonic curing occurs rapidly (sub‐millisecond), allowing the trapping of metastable states to form unique phases and nanostructures. We explored the possible underlying mechanism of photonic curing by incorporating laws of photophysics, photochemistry, and simulated temperature profile of thin film. The results show that photonic curing of spray coated 0.1 M molarity Si and Ge Acetyl Acetate precursor solution, at total fluence 80 J cm−2 can yield GeOx and SiOx nanostructures. The as‐synthesized nanostructures are ester functionalized due to photoinitiated chemical reactions in thin film during photonic curing. Results also showed that nanoparticle size changes from ~48 nm to ~11 nm if overall fluence is increased by increasing the number of pulses. These results are an important contribution towards large‐scale synthesis of the Ge and Si oxide nanostructured materials which is necessary for next‐generation energy storage devices.

AbstractPolymer ionogel (PIG) is a new type of flexible, stretchable, and ion‐conductive material, which generally consists of two components (polymer matrix materials and ionic liquids/deep eutectic solvents). More and more attention has been received owing to its excellent properties, such as nonvolatility, good ionic conductivity, excellent thermal stability, high electrochemical stability, and transparency. In this review, the latest research and developments of PIGs are comprehensively reviewed according to different polymer matrices. Particularly, the development of novel structural designs, preparation methods, basic properties, and their advantages are respectively summarized. Furthermore, the typical applications of PIGs in flexible ionic skin, flexible electrochromic devices, flexible actuators, and flexible power supplies are reviewed. The novel working mechanism, device structure design strategies, and the unique functions of the PIG‐based flexible ionic devices are briefly introduced. Finally, the perspectives on the current challenges and future directions of PIGs and their application are discussed.

A new method was proposed to synthesize aerogels based on Al2O3–TiO2 by the hydrolysis of mixed solutions of titanium tetrachloride and aluminum nitrate in the presence of propylene oxide, followed by supercritical drying of the obtained gels. The aerogels are characterized by a high specific surface area (140–500 m2/g) and a high specific porosity (1.7–2.7 cm3/g). Heat treatment of the Al2O3–TiO2 aerogels at temperatures up to 600°C does not lead to crystallization of titanium dioxide, whereas the formation of crystalline anatase in aerogels based on individual TiO2 is observed already at a temperature of 450°C. Using the standardized ISO 24443-2016 method, the SPF value of the obtained materials was determined, which turned out to be comparable to the characteristics of a commercial inorganic UV filter based on TiO2 (Kronos 1171). At the same time, the photocatalytic activity of the Al2O3–TiO2 aerogels turned out to be more than 120 times lower than the similar characteristics of the commercial UV filter based on titanium dioxide. The results obtained demonstrated that the Al2O3–TiO2 aerogels are promising as components of sunscreens.
