conducting polymer
@M03667@ material that exhibits bulk @E01926@.
  1. The @E01926@ of a conjugated polymer is markedly increased by doping it with an @E01988@ or acceptor, as in the case of polyacetylene doped with iodine.
  2. A polymer showing a substantial increase in @E01926@ upon @I03255@ with @UT07492@ or @VT07496@ light is called a photoconductive polymer; an example is poly(N-vinylcarbazole).
  3. A polymer that shows @E01926@ 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 @P04906@ as, e.g., in the case of fuel cells, it is called a @P04906@-conducting polymer.
  4. A polymer that shows electric semiconductivity is called a semiconducting polymer.
  5. @E01925@ of a non-conducting polymer can be achieved by dispersing conducting particles (e.g., metal, @C00824@) in the polymer. The resulting materials are referred to as conducting polymer composites or solid polymer-electrolyte composites.
