Abstract:
A visual display apparatus comprising a light transmitting substrate substantially transparent to predetermined optical wavelengths so that light entering one side of said substrate substantially passes through an opposite side of said substrate having a surface layer of a composition of matter comprising:an admixture of an abrasion resistant material selected from the group consisting of silicones, polysiloxanes, acrylates, methacrylates, epoxyacrylates, epoxymethacrylates, epoxies and styrenes; and an electrically conductive polymeric composition selected from the group consisting of substituted and unsubstituted polyparaphenylenevinylenes, substituted and unsubstituted polyanilines, substituted and unsubstituted polyazines, substituted and unsubstituted polythiophenes, substituted and unsubstituted poly-p-phenylene sulfides, substituted and unsubstituted polyfuranes, substituted and unsubstituted polypyrroles, substituted and unsubstituted polyselenophene, polyacetylenes formed from soluble precursors and combinations thereof; said admixture is light transmitting and is disposed on said light transmitting surface; the weight percent ratio of electrically conductive polymeric material to said abrasion resistant material being from about 2% to 50%; and said surface layer being a substantially uniform admixture of said abrasion/scratch resistant material and said electrically conductive polymer.
