Conducting polypyrrole electrochemically prepared from aqueous solutions

Polypyrrole (PPy) with charge transfer intercalated anions like TsO−, SO4= and NO3− prepared electrochemically from aqueous solutions showed good electrical conductivity. They are dense films with apparent densities close to their flotation densities. Voltage shorted compaction conductivity measurements showed some differences in the temperature dependence of conductivity of these differently intercalated PPy's. A PPy+ (TsO−) film was explored...
