▎ 摘　　要

NOVELTY - A composite material comprises a film-forming metal foam and a graphene component present on the surface of the metal foam or inside the metal foam. The metal foam includes pores. The pores have an average size of 10 mu m or less based on the long axis. USE - Composite material used for electromagnetic wave shielding sheet (claimed) for heat dissipation materials used for batteries and electronic devices. ADVANTAGE - The composite material has excellent heat dissipation performance, impact resistance and processability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of the composite material, which involves forming the graphene component on the surface of the film-forming metal foam; and (2) electromagnetic wave shielding sheet, which comprises the composite material.
