Many in-situ techniques are performed in order to determine the resistance of conducting polymer film. However, the resistance measured in solution can be the combination of polymer resistance and that of other components, such as resistance of supporting electrolyte. Therefore, in this work, the influence of the solution on the resistance of polypyrrole (PPy) film has been studied. PPy film was electrchemically synthesized onto the iron double-band electrode in a one step process from an aqueous solution of 0.1 M pyrrole and 0.1 M sodium salicylate. Resistance determination of PPy film was based on impedance spectroscopy measurements and was performed in-situ, ex-situ and in a function of electrode potential. Based on these measurements electrical equivalent circuit of PPy coated Fe electrode in contact with solution or with the air have been studied. It was noticed that the concentration of electrolyte in measuring solution did not influence on the polymer resistance measured by in-situ technique. It was also noticed that measurements of polymer resistance conducted insitu differ from that obtained in ex-situ experiments. The differences were related with the diffusion reactions occurring between the polymer film and air/solution.
