▎ 摘 要
NOVELTY - Preparation of graphene aluminum composite material includes filling nickel salt into pores of foam aluminum, heating for the first time and reducing nickel salt to elemental nickel to obtain foamed aluminum filled with elemental nickel; mixing with carbon-containing gas and heating for the second time to obtain foamed aluminum containing graphene sheets; and pressurizing to densify. USE - The method is for preparation of graphene aluminum composite material (claimed). ADVANTAGE - The method can reduce oxygen content in graphene aluminum-based composite material, increase its tensile strength, and achieve uniform dispersion of graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene aluminum composite material prepared by the method.
