▎ 摘　　要

NOVELTY - A graphene-polymer composite comprises shell containing amphoteric graphene, and core containing polymer. Amphoteric graphene has surface in which 0.2-60 hydrophilic groups based on 100 graphene carbon atoms are introduced. USE - Graphene-polymer composite (claimed). ADVANTAGE - The graphene-polymer composite has excellent physical property, electroconductivity and dispersibility of graphene without separate usage of surfactant or dispersion stabilizer, and reduced transformation of carbon-carbon double bonds which are delocalized on surface of the graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene-polymer composite, which involves polymerizing mixture containing vinyl monomer, initiator and amphoteric graphene.
