▎ 摘　　要

NOVELTY - A graphene composite material contains graphene layer (I), graphene layer (II) and graphene layer (III). The graphene layer (II) is provided with a supporting copper plate group (A) and supporting copper group (B). The supporting copper plate group (A) and supporting copper plate group (B) comprise supporting copper plates. The supporting plate comprises a supporting base and additive supporting plate to fixed on the supporting base. The top of additive supporting plate is recessed inward to form a pressure receiving groove. USE - Graphene composite material (claimed). ADVANTAGE - The graphene composite material has excellent heat conductivity, heat radiation effect, flexibility and prolonged shelf life. DETAILED DESCRIPTION - A graphene composite material contains graphene layer (I), graphene layer (II) and graphene layer (III). The graphene layer (II) is provided with a supporting copper plate group (A) and supporting copper group (B). The supporting copper plate group (A) and supporting copper plate group (B) comprise supporting copper plates. The supporting plate comprises a supporting base and additive supporting plate to fixed on the supporting base. The top of additive supporting plate is recessed inward to form a pressure receiving groove. The supporting copper plate group (A) and supporting copper plate group (B) are alternately relative to each other. An INDEPENDENT CLAIM is included for preparation method of graphene composite material.
