Synthesis and application of epoxy resins: A review

Epoxy resins have been widely used for coatings, electronic materials, adhesives, and matrices for fiber-reinforced composites because of their outstanding mechanical properties, high adhesion strength, good heat resistance, and high electrical resistance. The final properties of cured epoxy resins are affected by the type of epoxy resin, curing agent, and curing process. This paper aims to review the synthesis, curing process, and application of epoxy resins.

Graphical abstractIn this paper, we have reviewed various epoxy resins and curing agents. The properties of cured epoxy resins depend on the type of epoxy resin, curing agent, and curing process used. The toughness of epoxy resins can be improved by incorporating thermoplastic components, inorganics, carbon fibers, clay, and carbon nanotubes. Epoxy resins have a wide range of application including coatings, aerospace industry, electronic materials, and biomedical systems.Figure optionsDownload full-size imageDownload as PowerPoint slide
