| Abstract: | A series of electrically conducting pyrrole “black” polymers has been prepared by chemical oxidation of pyrrole with a variety of ferric salts. The synthesis and properties of these materials are described and compared with electrochemically-prepared analogs. Pyrrole “blacks” with strong acid anion “dopants” exhibited the highest conductivities, up to 62 Ω cm?1 for the triflate-doped polymer. The adjustability and ease of synthesis of the ferric-derived polypyrroles render these particularly promising for large-scale processing of conducting polymers. |
