DETAILED DESCRIPTION - The electrochemical gas bubble method for transferring large-area graphene based on the principle of electrochemical gas bubble stripping to realize transfer of large-area graphene, involves forming interface layer on surface of large-area graphene on an initial substrate, forming dense bond having high stability in electrolyte, with the surface of the graphene by the interface layer, forming transfer medium layer on the surface of the interface layer where the binding force between the transfer medium layer and the interface layer is greater than the peel force of electrochemical gas bubbling, binding graphene surface of graphene/interfacial layer/transfer medium composite film to the target substrate after the electrochemical gas is bubbled and stripped in the initial substrate, then peeling the interface layer from the graphene surface and realizing transfer of graphene to the target substrate, repeating the steps and transferring multilayer graphene.
