Abstract : In 1977, the first intrinsic electronically conducting organic polymer, doped polyacetylene, was reported, spurring interest in "conducting polymers." These polymers are a different class of materials than conducting polymers, which are merely a physical mixture of a non- conductive polymer with a conductive material such as metal or carbon powder. Initially these intrinsically conducting polymers were neither processable nor air stable. However, later generations of these polymers were processable into powders, films, and fibers to form electrically conductive blends. Applications of these polymers, especially polyanilines, have begun to emerge. These inelude blends and coatings for electrostatic dissipation and electromagnetic interference (EMI) shielding, electromagnetic radiation absorbers for welding (joining) of plastics, conductive layers for light- emitting polymer devices, and anticorrosion coatings for iron and steel.
