▎ 摘  要

NOVELTY - The method involves forming a metal nanomesh structure on a surface (100). A graphene sheet (130) is placed over the nanomesh structure. The graphene sheet is caused to adhere to the nanomesh structure for forming the transparent electromagnetic shield. A layer of metal is deposited over polystyrene microspheres assembled on the surface, and the polystyrene microspheres are removed from surface. The graphene sheet is removed from copper foil by chemical etching and bubble transfer. The graphene sheet is supported by a polymethyl methacrylate layer. USE - Method for fabricating transparent electromagnetic shield (claimed) e.g. hybrid mesh/graphene transparent electromagnetic shield. ADVANTAGE - The desired amount of electromagnetic shielding is provided, and an adequate amount of transparency is achieved, since the spacing between portions of the copper nanomesh is controlled. The electromagnetic shielding is increased while maintaining transparency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a transparent electromagnetic shield. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the final stage in the process for fabricating hybrid mesh/graphene transparent electromagnetic shield.
