▎ 摘　　要

NOVELTY - The copper seed and graphene composite multilayer cooling film has graphene layer (1) and copper layer (2). USE - Copper seed and graphene composite multilayer cooling film. ADVANTAGE - Provides high efficiency multilayer cooling film since the graphene layer and copper layer are alternately formed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of copper and graphene composite multilayer cooling film. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic illustration of the copper seed and graphene composite multilayer cooling film. Graphene layer (1) Copper layer (2)
