Abstract
A method of preparing a surface for exposure to an electron beam includes forming a water soluble self-acid-doped conducting polyaniline material. The water soluble self-acid-doped conducting polyaniline material may be poly(aniline-co-N-propanesulfonic acid aniline). The polyaniline material may be mixed with polyvinyl alcohol and applied to a surface prior to subjecting the surface to an electron beam. The electron beam is then transmitted through the material and onto the surface, with the polyaniline material acting as a charge dissipation layer.
