Conductive film: a composite material that generally forms a conductive layer on an ordinary plastic film, including a single conductive film and a composite conductive film, such as a multi-layer film combined with metal and metal oxides. Ester, polycarbonate, polypropylene, polystyrene, nylon, polyimide, polyvinyl chloride, polyethylene, etc. Production of conductive film: In addition to the general calendering method, the method of forming a conductive layer on the surface of the plastic film is mainly used, such as vacuum coating method (vacuum evaporation, ion spraying), electroplating method, thermal decomposition method, coating method, etc.
