Term: intrinsically conducting polymer
https://doi.org/10.1351/goldbook.IT07208

Definition:
electrically conducting polymer composed of macromolecules having fully conjugated sequences of double bonds along the chains.

Notes:
0) The bulk electrical conductivity of an intrinsically @CT07170@ is comparable to that of some metals and results from its macromolecules acquiring positive or negative charges through @O04362@ or reduction by an electron-acceptor or -donor (charge-transfer agent), termed a @DT07203@.
1) Examples of intrinsically conducting polymers are polyacetylene, polythiophene, polypyrrole, or polyaniline. Unlike @M03667@ electrolytes, in which charge is transported by dissolved ions, charge in intrinsically conducting polymers is transported along and between polymer molecules via generated charge carriers (e.g., holes, electrons).
2) An intrinsically @CT07170@ should be distinguished from a @CT07201@ and from a @ST07227@.
