▎ 摘　　要

NOVELTY - Composite radiating film comprises a heat conducting middle layer and a first boron nitride layer arranged on the opposite two side surfaces of the heat conducting middle layer, where the heat conducting middle layer comprises a layer of graphite sheet. USE - Composite radiating film. ADVANTAGE - The film has good electric insulation and radiating effect at the same time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the composite heat dissipation film, which involves laminating the thermally conductive intermediate layer and the first boron nitride layer together for calendering treatment, and then performing heat treatment at a temperature of 800-1700 degrees C.
