▎ 摘  要

NOVELTY - Transferring graphene film involves forming surface small molecule polymer the metal substrate of the graphene molecule to obtain small molecule polymer, to obtain small molecule layer/graphene film metal substrate complex, an organic auxiliary support layer is formed on the small molecular polymer, a heat release adhesive tape layer is adhered on the organic auxiliary support layer surface, the metal substrate is removed to obtain the heat release adhesive tape layer/organic auxiliary support layer/small molecule polymer, the small molecule layer graphene composite, attaching the side the graphene release adhesive tape layer/organic auxiliary support layer/small molecule polymer layer/graphene heating remove heat releasing adhesive tape layer and organic solvent, the organic auxiliary support layer and the small molecule polymer. USE - Method for transferring a graphene film. ADVANTAGE - The method enables avoiding removing the residue of the organic auxiliary support layer on the graphene surface.
