ABSTRACT:
Electrically conductive and abrasion resistant polymeric compositions, methods of fabrication thereof and uses thereof are described. Admixtures of abrasion resistant materials and electrically conductive polymeric materials are formed. Many of these admixtures are light transmitting and can be used as an abrasion resistant light transmitting electrostatic discharge layers. The light transmitting discharge layer is useful as a surface coating for visual displays such as CRT screens to avoid electrostatic accumulation of dust and scratching. The compositions can be admixtures of abrasion resistant silicones, polysiloxanes, acrylates, epoxies, methacrylates, epoxyacrylates, epoxymethacrylates, styrenes and electrically conductive polymers selected from the group of substituted and unsubstituted polyanilines, polyparaphenylenevinyles, substituted and unsubstituted polythiophenes substituted and unsubstituted poly-p-phenylene sulfides, substituted and unsubstituted polyfuranes, substituted and unsubstituted polypyrroles, substituted and unsubstituted polyselenophenes, polyacetylines formed from soluble precursors, combinations thereof and blends thereof with other polymers. The compositions can be a layer of an electrically conductive polymer with an abrasion resistant layer thereover.
