▎ 摘　　要

NOVELTY - Graphene thermal and heat radiation reflective film comprises 50-99 wt.% substrate and 1-50 wt.% graphene, where substrate is selected from polyethylene terephthalate, polyvinyl chloride, polyethylene, polyphthalamide, low-density polyethylene and biaxially oriented polypropylene. USE - Graphene thermal and heat radiation reflective film. ADVANTAGE - The graphene thermal and heat radiation reflective film is simple, cost-effective, and suitable for large-scale popularization and application, has excellent heat conducting and has radiating performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene thermal and heat radiation reflective film, which involves preparing substrate layer provided on one or both sides of substrate layer with a metal coating to obtain a reflective film body, where metal coating provided on one side of the front surface of the reflective film body, other side of the reflective film body back, reflective film body back coating substrate, and graphene layer on substrate layer.
