Polymeric material that exhibits bulk
electric conductivity.
Notes:
-
See also: conductivity.
-
The electric conductivity of a conjugated polymer is markedly increased by doping it with an electron donor or acceptor, as in the case of polyacetylene doped with iodine.
-
A polymer showing a substantial increase in electric conductivity upon irradiation with ultraviolet or visible light is called a photoconductive polymer; an example is poly(N-vinylcarbazole) (See also: photoconductivity).
-
A polymer that shows electric conductivity 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 proton as, e.g., in the case of fuel cells, it is called a proton-conducting polymer.
-
A polymer that shows electric semiconductivity is called a semiconducting polymer (See also: semiconductor).
-
Electric conductance of a non-conducting polymer can be achieved by dispersing conducting particles (e.g., metal, carbon black) in the polymer. The resulting materials are referred to as conducting polymer composites or solid polymer-electrolyte composites.
