▎ 摘　　要

NOVELTY - Graphene composite foam film comprises 40-95 wt.% graphene foam film and a high polymer, where the graphene foam film is provided with pores and high polymer is distributed in the pores on the surface of the graphene foam film. USE - Used as graphene composite foam film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for prepairing the graphene composite foam film comprising (i) taking a graphene foam film, (ii) arranging second pore penetrating up and down along the thickness direction of the graphene foam film, (iii) soaking the graphene foam film provided with the second pores in a high molecular polymer or a solution of the high molecular polymer, and (iv) taking out the graphene foam film and fully curing the graphene foam film.
