Epoxy resins are widely used for various applications including coating, adhesives, structural materials and electrical insulation due to excellent thermal and mechanical properties. Imparting electrical conductivities to cured epoxy resins is demanded for some application, and graphene is considered as one of conductive fillers due to the excellent electrical and mechanical. In this study, graphene nanoplates (GNP) were obtained by sonication of natural graphites in N-methyl-2-pyrrolidone and the GNP was incorporated into an epoxy resin. In order to improve the percolation of GNPs in the nanocomposites, charge transfer complex formation was induced with n-doped GNP and p-doped GNP in the epoxy resin. It was found that the heat resistance and electrical conductivity of the nanocomposites with n-doped GNP and p-doped GNP were increased compared with the nanocomposite with GNPs without doping. |
