| dc.description.abstract | Polyaniline (PANI) was prepared electrochemically by the pulse and potential cycling methods at gold and platinum electrodes, respectively. Thin and thick films were prepared by the latter method. Square-wave and ac-voltammetric methods were employed to investigate the leucoemeraldine/emeraldine redox couple. Two well-separated cunent peaks were obse!ved in the thick films suggesting a two-step reaction in the oxidation process. The effect of supporting electrolytes on the ac-voltammetric behavior of PANI was also investigated. The positions of the current peaks seem to be influenced by the size of the anion. The obselved two-current peaks might be due to a two-step reaction in the transformation of leucoemeraldine to emeraldine. | en_US |
