Abstract
An electrically conductive polymer, doped with at least one electron acceptor or electron donor, which polymer has a main chain of arylene units and interspersed regularly or irregularly between them one or more chalcogen atoms or groups of such atoms, especially sulfur and/or oxygen atoms; especially poly(p-phenylene sulfide) doped with an arsenical doping agent. These doped polymers have utility similar to semiconductors or to metals, particularly where light weight is desired, for example in battery electrodes.
Claims20
An electrically conductive organic polymeric composition comprising at least one thermoplastic and/or solvent processible polymer and at least one electron acceptor or electron donor dopant or mixture thereof, which polymer has a main chain consisting essentially of (1) arylene units selected from the group consisting of paraphenylene units, meta-phenylene units, biphenylene units, naphthalene units and substituted forms thereof, and (2) interspersed between arylene units therein, regularly or irregularly along the chain, one or more chalcogen atoms or groups of such atoms;
- said composition having conductivity at 25.degree. C. of at least 10.sup.-7 reciprocal ohm-cm.
