▎ 摘　　要

NOVELTY - Light is irradiated to a mixture containing radically polymerizable vinyl monomer(s) and oxidation graphene, and vinyl monomer is radically polymerized using oxidation graphene as polymerization initiator to obtain graphene polymer composite material. USE - Manufacture of graphene polymer composite material (claimed) used as functional material. ADVANTAGE - The method efficiently provides graphene polymer composite material having excellent external appearance, electrical conductivity, Young's modulus, tensile strength, elasticity modulus and abrasion resistance, by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene polymer composite material, which has polymer chain whose one portion is coupled with oxidation graphene.
