摘要：

Cyclic voltammetry and electrochemical quartz crystal microbalance techniques were combined to study the ionic exchange process in polypyrrole doped with the anionic surfactant, dodecylbenzenesulfonate. A quantitative analysis of the results indicates a doping degree of 20% after dectropolymerization. Studies performed in monomer-free solutions show that both anions and cations of the electrolytes play an important role in the redox process. Quantitative calculations also take into account the transfer of neutral species like solvent molecules.
