▎ 摘　　要

NOVELTY - Transferring large-area graphene by regulating and controlling bonding force, comprises firstly forming a transfer medium on the surface of large-area graphene positioned on an initial matrix; then separating a 'transfer medium/graphene' composite film from the initial matrix; further bonding the surface of graphene of the 'transfer medium/graphene' composite film with a target matrix, and realizing the transfer of graphene to the target matrix after stripping the transfer medium. USE - The method is useful for transferring large-area graphene by regulating and controlling bonding force (claimed). ADVANTAGE - In the method, the transfer medium is taken as a support layer in the process of transferring graphene, and the adhesive with high adhesion force is simultaneously adopted for improving the bonding force between graphene and the target matrix, thus improving the structural integrity of large-area graphene during transfer and easy transfer of multiple layers of grapheme. The method is compatible with a roll-to-roll process, and large-scale and continuous transfer can be realized. DETAILED DESCRIPTION - Transferring large-area graphene by regulating and controlling bonding force, comprises firstly forming a transfer medium on the surface of large-area graphene positioned on an initial matrix, where the bonding force between the transfer medium and graphene is weak bonding force or the bonding force can be reduced to weak bonding force; then separating a 'transfer medium/graphene' composite film from the initial matrix; further bonding the surface of graphene of the 'transfer medium/graphene' composite film with a target matrix through an adhesive with high adhesion force, and realizing the transfer of graphene to the target matrix after stripping the transfer medium; and repeating the steps to transfer multiple layers of graphene. The method specifically comprises (i) binding the initial substrate surface of graphene with transfer media, and binding the transfer medium/graphene composite membrane with the initial separating substrate; (ii) binding the transfer medium/graphene composite film graphene surface with the target substrate by an adhesive; and (iii) separating the transfer media from the graphene.
