Conductive anti-reflective films
A method of applying a transparent conductive film to a polymeric substrate having a desired textured therein is provided. The method includes the steps of providing a polymeric material having a texture disposed therein and conformally applying a transparent conductive material to the molded polymeric material to produce a conformal transparent conductive film thereon. The conformal transparent conductive film has a texture corresponding to the texture of the polymeric material and has a period that is not larger than the wavelength of visible light, whereby the conformal transparent conductive film is antireflective.
