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:

Determination of carrier mobility in MEH-PPV thin-films by stationary and transient current techniques
Cleber A. Amorim,Marco Roberto Cavallari,G. Santos,Fernando Josepetti Fonseca,Adnei Melges de Andrade,S. Mergulhão +5 more
TL;DR: In this paper, the authors investigated the charge transport and shelf-degradation of MEH-PPV thin-films through stationary (e.g., current versus voltage) and transient (i.e., current-limited current) current techniques.

Polypyrrole-bearing conductive composite prepared by an inverted emulsion pathway involving nonionic surfactants
Yue Sun,Eli Ruckenstein +1 more
TL;DR: In this article, an inverted emulsion was generated by dispersing an aqueous solution of FeCl3 (as oxidant and dopant) in an organic solution (six different solvents have been employed) of a host polymer (styrene-butadiene-styrene (SBS), styrene-ethylene-butylene-structure (SES), and nonionic surfactant with stirring, and polypyrrole was thus formed rapidly (10-15 min). Methanol was introduced to precipitate the composite after polymerization was completed.
