Unlocking the Potential of Covalent Organic Frameworks (COFs) in Corrosion Prevention: A Review of Recent Progress and Future Directions

Corrosion remains a critical challenge across various industries, particularly affecting the longevity and safety of metallic materials. To combat this issue, intelligent anti‐corrosive coatings have emerged as a promising solution, incorporating micro/nano carriers that store and release corrosion inhibitors in response to specific stimuli. These advanced coatings have demonstrated the ability to significantly enhance the electrochemical impedance of steel, offering superior protection compared to conventional coatings. Among the innovative materials explored for this purpose, covalent organic frameworks (COFs) have garnered attention for their exceptional potential as nanocarriers. COFs are characterized by their high surface area, tunable porosity, and chemical versatility, making them ideal for improving corrosion resistance. This review highlights recent advancements in the use of COFs for intelligent anti‐corrosive coatings, focusing on essential design factors such as carrier compatibility, stability, stimuli‐responsive properties, synthesis techniques, and underlying mechanisms. Despite their relatively recent discovery, COFs have shown remarkable promise in enhancing the durability and reliability of anti‐corrosive coatings. The review also addresses the existing challenges for COF‐based nanocarriers in corrosion protection and explores their future potential in this field.
