▎ 摘　　要

NOVELTY - Preparing graphene-carbon composite material, comprises: (a) mixing aniline monomer, oxidant and liquid crystalline graphene oxide, and reacting to obtain graphene oxide-polyaniline composite; and (b) mixing the graphene oxide-polyaniline composite with an activator, and reacting to obtain graphene/carbon composite material. USE - The method is useful for preparing graphene-carbon composite material (claimed). ADVANTAGE - The method adopts mixing of aniline monomer and liquid crystalline graphene oxide as raw material to produce polyaniline at the interlayer of graphene oxide, which can effectively prevent agglomeration phenomenon in the activation process and simultaneously allow the attachment of polyaniline to graphene surface to form porous carbon material during the activation process to ensure that the obtained graphene-carbon composite material has good capacitance performance and cyclic performance.
