Thick, 3-14 mil, free-standing polypyrrole films incorporating a large variety of anion ''dopants'' were anodically deposited from aqueous electrolytes. Four-point probe conductivity and x-ray diffraction measurements were made and compared. Aromatic and very large amphiphilic sulfonate dopants provided the highest conductivities (up to 120 S cm/sup -1/), stabilities, mechanical properties, and apparent order. The dodecylbenesulfonate system was the most stable, being unaffected by even concentrated aqueous ammonia. A qualitative voltammetric technique which probes the relative order in as-deposited thin films is introduced.
