▎ 摘　　要

NOVELTY - A fluororesin/graphene composite is obtained by carrying out hot-press molding of fluororesin/graphene core-shell particles. Graphene has three-dimensional network-like distribution. The average particle size of fluororesin is 50-500 mu m. Fluororesin is filled in the three-dimensional graphene network. The content of graphene in fluororesin/graphene composite is 0.01-10 vol.%. USE - Fluororesin/graphene composite is used for manufacturing electroconductive material (claimed). ADVANTAGE - The fluororesin/graphene composite has low percolation concentration and high conductivity, and can be manufactured efficiently and economically by simple method with reduced consumption of energy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of fluororesin/graphene composite, which involves dispersing fluororesin and graphene oxide in a liquid medium, adding flocculant, flocculating, obtaining fluororesin/graphene oxide core-shell particles, dispersing obtained particles in a liquid medium, reducing graphene oxide under reflux, obtaining fluororesin/graphene core-shell particles, and thermoforming.
