▎ 摘  要

NOVELTY - Copper foil graphite sheet comprises a copper foil, a graphene layer continuously deposited on the surface of the copper foil and a nickel-plated layer distributed in a non-continuous island shape between the copper-copper foil and the graphene layer, where the nickel plated layer is plated on the copper surface of copper foil. The graphene at least partially grows in the nickelplated layers through chemical vapor deposition. USE - Copper foil graphite sheet for a radiating assembly of a flat computer and an intelligent mobile phone intelligent device i.e. laptop computer. Can also be used for a notebook computer. ADVANTAGE - The copper foil graphite sheet can ensure stable radiating effect in the using process, avoiding the graphene layer peeling off from the surface of the copper foil. The graphene sheet layer is benefit from the intercalation and intermolecular interaction between them, and can form a continuously stable graphene layer. The nickel plating layer can assist the heat transfer in the thickness direction of the graphene at a certain degree of the heat in the position, so that the graphene can realize the transmission of the plane direction more quickly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the manufacturing technique of the copper foil graphite sheet.
