▎ 摘　　要

NOVELTY - Preparing graphene aerogel aluminum composite material, comprises (i) preparing a graphene aerogel; (ii) heating the aluminum ingot into a liquid state to become an aluminum liquid; and (iii) immersing the graphene aerogel in the aluminum liquid, for 1 minute-1 hour, air cooling, and taking out. USE - The method is useful for preparing graphene aerogel aluminum composite material. ADVANTAGE - The graphene aerogel aluminum composite material has unicom structure, so that the composite material has high thermal conductivity and electrical conductivity.
