▎ 摘　　要

NOVELTY - A graphene composite powder material is obtained by mixing graphene powder material and polymer. The polymer is uniformly covered on the surface of the graphene material, such that adjacent graphene materials are spaced by the polymer. The apparent density of the graphene powder material is 0.02 g/cm3 or more. USE - Graphene composite powder material (claimed). ADVANTAGE - The method provides single metal atoms on graphitic surface by simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene composite powder material, which involves adding polymer monomer, graphene material and micro-nano structural material to water, mixing uniformly, obtaining mixed solution, adding water-soluble initiator, reacting at 30-100 degrees C for 1-10 hours, and drying. The mass ratio of polymer monomer, graphene material and micro-nano structural material is (0.01-1):(0.1-1):(5-1). The mass ratio of water-soluble initiator and polymer monomer is 1:10-1:100.
