▎ 摘　　要

NOVELTY - Graphene flexible composite layer comprises a first graphene film layer, a first metal substrate, a non-metal substrate, a second metal substrate, and a second graphene film layer sequentially. USE - Graphene flexible composite layer used in electromagnetic shielding, antistatic, electrical and thermal conductivity product (claimed). ADVANTAGE - The graphene flexible composite layer improves productivity for preparing graphene film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a graphene flexible composite layer, which involves: (A) placing flexible composite layer of first metal substrate-non-metal substrate-second metal substrate on driven roller and driving roller of roll-to-roll continuous growth equipment; and (B) growing graphene continuously on flexible composite layer of first metal substrate-non-metal substrate-second metal substrate to obtain a graphene flexible composite layer or graphene grown on graphene flexible composite layer.
