▎ 摘　　要

NOVELTY - A polyvinylidene fluoride/graphene composite material consists of 65-95 wt.% polyvinylidene fluoride, 0.1-20 wt.% graphite, 0.1-10 wt.% dispersing agent, 0-10 wt.% wetting agent, 0-5 wt.% surface active agent, and 0-2 wt.% compatibilizer. USE - Polyvinylidene fluoride/graphene composite material for piezoelectric material, thermoelectric material, dielectric material and conductive material. ADVANTAGE - The polyvinylidene fluoride/graphene composite material is easily manufactured without affecting environment and without using solvent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of polyvinylidene fluoride/graphene composite material, which involves adding polyvinylidene fluoride, graphite, dispersing agent, wetting agent, surface active agent, and compatibilizer to high-speed mixer, mixing, and melting mixed material at 180-230 degrees C.
