Resumo: In order to investigate the electrochemical behaviour and morphology under different experimental conditions of poly-N-methylpyrrole doped with sodium p-toluensulphonate (NaTsO) in aqueous medium, the doped polymer was potentiostatically synthesized at four potential values: 0.6, 0.8, 0.9 and 1.0 V. The morphological study reveals a compact texture in these polymeric films; after being submitted to a positive potential those films were wrinkled. Cyclic voltammetry was used to characterize polymer films (pNMPy/TsO). The corresponding voltammograms revealed a reversible doping/de-doping process in those films obtained at ηp = 0.8 V. Different parameters such as: negative potential limit (Ei), positive potential limit (Ef), sweep rate (v) and continuous cycling were varied.
