Characterization of capacitance, thermal conductivity, and specific heat capacity of cold welding epoxy matrix composites with graphite inclusions to be used as electrolyte medium in the design of supercapacitors

Cold welding is typically used for joining and repairing parts in the industry. However, many other epoxy resin-based adhesives have been shown to have a future as sensors or supercapacitors, and this leads us to seek to manipulate their physical properties. For these purposes, commercial cold welding matrix composites with graphite inclusions are proposed to be studied by varying their volume ratio. Thermal conductivity and specific heat capacity of the samples were measured by laser flash and thermal relaxation techniques, and capacitance was measured by electrical impedance spectroscopy. These materials are studied to be used as electrolyte medium in the design of double-layer supercapacitors.
