@[email protected] material that exhibits bulk @[email protected]
Notes:
- The @[email protected] of a conjugated polymer is markedly increased by doping it with an @[email protected] or acceptor, as in the case of polyacetylene doped with iodine.
- A polymer showing a substantial increase in @[email protected] upon @[email protected] with @[email protected] or @[email protected] light is called a photoconductive polymer; an example is poly(N-vinylcarbazole).
- A polymer that shows @[email protected] due to the transport of ionic species is called an ion-conducting polymer; an example is sulfonated polyaniline. When the transported ionic species is a @[email protected] as, e.g., in the case of fuel cells, it is called a @[email protected] polymer.
- A polymer that shows electric semiconductivity is called a semiconducting polymer.
- @[email protected] of a non-conducting polymer can be achieved by dispersing conducting particles (e.g., metal, @[email protected]) in the polymer. The resulting materials are referred to as conducting polymer composites or solid polymer-electrolyte composites.
