Abstract:

The applicability of the concept of doping is the unifying theme which distinguishes a certain class of organic polymers - conducting polymers - from all others. Doping results in dramatic electronic and magnetic charges with a concomitant increase in conductivity to, or approaching, the metallic regime. Doping phenomena and the chief types of dopable organic polymers are described with particular emphasis on polyaniline which is presently being commercialized on a relatively large scale and is the leading conducting polymer for technology, although closely followed by polythiophene derivatives. Polyaniline shows considerable promise for electromagnetic interference EMI shielding and is already used in commercial rechargeable batteries. Leading potential technological applications utilize polyaniline film membranes for gas separations and polyphenylenevinylenes as light-emitting diodes. Additional potential applications of conducting polymers such as electrochromic windows, redox capacitors, chemical sensors, etc. are also described briefly.
