▎ 摘  要

NOVELTY - A surface-modified graphene comprises graphene powder and at least one surface-modified layer. The surface-modified layer comprises surface-modifying agent and at least two functional groups disposed at two ends of the surface-modifying agent. The one functional group generates a chemical bond with organic functional group on the surface of the surface-modified graphene powder, and other functional group forms a surface characteristic of the surface-modified graphene. The surface-modifying agent comprises coupling agent, aliphatic acid and resin. USE - Surface-modified graphene (claimed). ADVANTAGE - The surface-modified graphene powder has excellent dispersibility with respect to solvent, endophilicity between graphene powder and organic polymer, and durablility.
