Abstract : The electrical conductivities of the intrinsically conducting polymer systems now range from that typical of insulators (<l0-10(ohms-1-cm)-1) to that typical of semiconductors such as silicon (-10-5 S/cm) to greater than 10(4) S/cm (nearly that of a good metal such as copper, 5 x 10(5) S/cm). The origin of the conductivity in these polymers is reviewed. Applications of these polymers, especially polyanilines, have begun to emerge. These include coatings and blends 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.
