▎ 摘　　要

NOVELTY - Substrate-free graphene heat-conducting film comprises a graphene layer, an acrylic adhesive layer coated with the top surface of the graphene layer, a light release film attached with the top surface of the acrylic adhesive layer, and an oriented polypropylene insulating film provided with the lower surface of the graphene layer. USE - Used as substrate-free graphene heat-conducting film. ADVANTAGE - The heat-conducting film has high heat conduction coefficient of 1700-1900 W/m-K, and is economical and convenient to manufacture. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the substrate-free graphene heat-conducting film.
