Electrically conductive transparent plastic material

Abstract

Abstract An electrically conductive clear transparent self-supporting plastic sheet consisting of a homogeneous solid molecular mixture of a clear transparent conductive polymer and a film forming clear transparent polymer is obtained by combining a quaternary ammonium polyelectrolyte, such as polydimethyl diallyl ammonium chloride, with a film forming polymer, such as polyvinyl alcohol, and a mutual solvent, such as water. The mixture is then cast onto a smooth surface, the mutual solvent evaporated, and the resultant sheet material stripped from the casting surface to obtain a sheet of electrically conductive clear transparent plastic material useful as a conductive plastic or, after coating with a charge retentive film, as an electrographic recording medium.
