1. A method for manufacturing a metal mesh touch screen, comprising:
selecting a first metal foil with a first rough surface and a second rough surface, covering the first rough surface of the first metal foil with a polyethylene terephthalate (PET) protective film, attaching a first adhesive layer with a light release film removed to the second rough surface of the first metal foil, removing the PET protective film on the first rough surface of the first metal foil and coating a photosensitive material on the first rough surface of the first metal foil, and exposing, developing, etching and demoulding to obtain a first functional electrode layer with a first metal mesh wiring;
selecting a second metal foil with a first rough surface and a second rough surface, covering the first rough surface of the second metal foil with the PET protective film, attaching a second adhesive layer with a light release film removed to the second rough surface of the second metal foil, removing the PET protective film on the first rough surface of the second metal foil and coating the photosensitive material on the first rough surface of the second metal foil, and exposing, developing, etching and demoulding to obtain a second functional electrode layer with a second metal mesh wiring;
blackening the first functional electrode layer and the second functional electrode layer respectively to obtain a targeted first functional electrode layer and a targeted second functional electrode layer; and
removing a heavy release film of the first adhesive layer and attaching the first adhesive layer to a side of the second functional electrode layer of the targeted second functional electrode layer away from the second adhesive layer to obtain a targeted metal mesh touch screen.
