▎ 摘　　要

NOVELTY - Changing the coupling performance of double-layer graphene comprises providing a graphene sample and a substrate, where the graphene sample is a double-layer graphene, transferring the graphene sample to the substrate, forming a combined body, heating the combined body in a closed container filled with a solvent to a preset temperature and maintaining the preset time, where the position of the combined body in the closed container is higher than the liquid level of the solvent and cooling to obtain the target graphene product. USE - The method is useful for changing the coupling performance of double-layer graphene. ADVANTAGE - The method: has single step; and is simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a double-layer graphene.
