| Zusammenfassung: | The invention aims to provide a graphene-metal composite film and a manufacturing method thereof. The graphene-metal composite film comprises a graphene film, a first metal coating and a second metal coating, wherein the first metal coating is formed on one side of the graphene film through magnetron sputtering or electroplating, and the second metal coating is formed on the side, away from the graphene film, of the first metal coating through magnetron sputtering or electroplating. The specific preparation method comprises the following steps: carrying out roughening modification treatment on the surface of the provided graphene film, then plating the surface of the graphene film with a first metal coating, carrying out laser irradiation treatment on the first metal coating, and finally plating the first metal coating with a second metal coating. The bonding strength of the metal coating and the surface of the graphene film is improved through roughening modification treatment of the surface of the graphene |
