摘要：

The electrochemical behaviour, FTIR spectrum and the morphology of polypyrrole-polystyrenesulphonate (PPy-PSS) films obtained potentiostatically at 0.6 V in a 0.05 M Py + 1.7 x 10(-2) M NaPSS medium have been analysed. Different electrochemical parameters have been modified in order to establish the first polaron formation, the reversibility of the redox process and the doping mechanism. The FTIR spectrum confirms the existence of C=O groups in the film structure and two possible explanations arc suggested. SEM reveals a higher homogeneity in these films than in PPy films doped with smaller counterions.
