▎ 摘  要

NOVELTY - The method comprises introducing a hydrophilic functional group in a graphene surface by bonding a conjugated organic polymer and graphene to obtain a graphene surface-modified with hydrophilicity, applying a polarity amine group polymeric compound, an aromatic vinyl polymeric compound or a unsaturated carboxylic acid ester polymeric compound on the surface, introducing a hydrophobic functional group in the graphene surface-modified with hydrophilicity to obtain a graphene surface-modified with hydrophobicity, and dispersing the surface-modified graphene in a polar or non-polar solvent. USE - The method is useful for modifying a surface of graphene using a conjugated organic polymer (claimed), where the graphene is useful for forming a nano-composite material. ADVANTAGE - The method is capable of modifying the surface of the graphene without any damage, and provides excellent electrical, thermal and physical properties to the graphene. DETAILED DESCRIPTION - The method comprises introducing a hydrophilic functional group in a graphene surface by bonding a conjugated organic polymer and graphene to obtain a graphene surface-modified with hydrophilicity, applying a polarity amine group polymeric compound, an aromatic vinyl polymeric compound or a unsaturated carboxylic acid ester polymeric compound on the surface, introducing a hydrophobic functional group in the graphene surface-modified with hydrophilicity to obtain a graphene surface-modified with hydrophobicity, and dispersing the surface-modified graphene in a polar or non-polar solvent. An assistive monomer is further used for the surface modification of the graphene.
