▎ 摘 要
NOVELTY - Preparing graphene aluminum composite material comprises preparing aluminum film on graphene powder using magnetron sputtering method to obtain modified graphene powder, adding modified graphene powder into molten aluminum liquid and stirring uniformly, dispersing the modified graphene powder in the aluminum liquid to obtain mixed system, heating and curing the mixed system. USE - The method is useful for preparing graphene aluminum composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIMS are also included for graphene aluminum composite material obtained by the above method.
