▎ 摘　　要

NOVELTY - Preparing graphene aluminum composite material comprises providing graphene aerogel, using vacuum evaporation method to obtain aluminum film on the surface of the graphene aerogel, stirring the graphene aerogel with the aluminum film formed on the surface to obtain graphene powder with the aluminum film formed on the surface, compounding the graphene powder with the aluminum film formed on the surface and the aluminum matrix by stirring casting method. USE - The method is useful for preparing graphene aluminum composite material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) graphene aluminum composite material prepared by above mentioned method; and (2) cable or wire, comprising the graphene aluminum composite material.
