Method for transferring CVD graphene on metal copper surface to target substrate surface

The invention discloses a method for transferring chemical vapor deposition graphene on a metal copper surface to a target substrate surface, and belongs to the technical field of materials. The method comprises the following steps: firstly, growing on a copper foil surface through a chemical vapor deposition method, so as to obtain graphene; by taking a copper foil as an anode, a glassy carbon sheet as a cathode, and agar gel of copper sulfate as solid electrolyte, dissolving the copper foil by using an electrochemical method, depositing on the surface of a glassy carbon electrode and forming a copper film; and finally, dissolving and removing the agar gel in hot water to obtain a graphene film which is transferred to the target substrate surface, and obtaining the metal copper foil on the surface of the glassy carbon electrode for growth of the graphene. By using the method, green and efficient transfer of the graphene on the surfaces of a plurality of target substrates can be achieved; cyclic utilization of the metal copper can be achieved; the preparation cost of the graphene film is reduced; and large-scale application of the graphene in the fields of conductive films and the like is promoted.
