TLDR
When silvery films of the semiconducting polymer, trans polyacetylene, (CH)x, are exposed to chlorine, bromine, or iodine vapour, uptake of halogen occurs, and the conductivity increases markedly (over seven orders of magnitude in the case of iodine) to give silvery or silvery-black films, some of which have a remarkably high conductivity at room temperature.Abstract:

Development of an electrochemical sulfite biosensor by immobilization of sulfite oxidase on conducting polyaniline film
TL;DR: In this article, a biosensor was developed for the determination of sulfite, based on electrochemical incorporation of free sulfite oxidase into polyaniline aluminum modified electrode.
Journal ArticleDOI
Electronic properties of pure and doped polyacetylenes
TL;DR: In this article, it was deduced that the sudden occurrence of high electrical conductivity in polyacetylenes doped with electron donors or acceptors is essentially brought about by the transfer of an electron from the highest occupied band (pi ) or to the lowest unoccupied band ( pi*) of the parent polyacetylene.

Thermoelectric measurements of PEDOT:PSS/expanded graphite composites
TL;DR: The thermoelectric properties of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)/expanded graphite films were cast as thin films with different expanded graphite contents at room temperature as discussed by the authors.
