NOVELTY - Method for nondestructively transferring graphene from metal surface to surface of target substrate involves growing graphene on surface of copper foil, coating surface of graphene with polymethyl methacrylate film, floating foil in aqueous solution of ferric chloride, obtaining polymethyl methacrylate/graphene composite film, adsorbing composite film on surface of organic thin film, washing with deionized water, transferring composite film to surface of target substrate, dissolving resultant product in solvent, and removing polymethyl methacrylate on the surface. USE - Method for nondestructively transferring graphene from metal surface to surface of target substrate e.g. glass substrate, quartz substrate or polyethylene terephthalate thin film substrate (all claimed). ADVANTAGE - The method enables reliable nondestructive transfer of large-sized graphene from metal surface to surface of target substrate with reduced damage rate of graphene. DETAILED DESCRIPTION - Method for nondestructively transferring graphene from metal surface to surface of target substrate involves growing graphene on surface of copper foil, coating surface of graphene with polymethyl methacrylate film as support layer, floating copper foil in aqueous solution of ferric chloride to corrode and remove copper, obtaining polymethyl methacrylate/graphene composite film, enabling organic thin film with static electricity in a friction manner to approach the polymethyl methacrylate/graphene composite film which is floated on the liquid surface, adsorbing the graphene/polymethyl methacrylate composite film on surface of the organic thin film by using electrostatic effect, washing the composite film with deionized water to remove ferric chloride solution attached to surface of graphene, releasing static electricity on the surface of the organic thin film, separating the composite film from organic thin film, floating the composite film on water surface, washing graphene, transferring composite film to surface of target substrate, dissolving resultant product in solvent, and removing polymethyl methacrylate on the surface.
