▎ 摘　　要

NOVELTY - A composite material comprises a 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 20-380 mu m. USE - Composite material is used as heat dissipation materials for batteries and electronic devices. ADVANTAGE - The composite material has improved heat dissipation performance, impact resistance, processing property and pore characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the composite material, which involves forming the graphene component on the surface of the metal foam.
