“…Transmission line models composed of a resistance due to electron transport along and between chains in parallel with a resistance associated with ionic transport have become popular [4][5][6]. In general, the resistance due to movement of ions through pores is less than the resistance due to redox conduction of electrons through the layer (3J.…”

Polypyrrole was deposited from solutions of NaClO4 and NaDBS, where DBS is dodecylbenzenesulfonate, in aqueous solution and characterized by voltammetry. It is found that the absence of the so‐called ‘double layer charging current’ during cyclic voltammetry of the layers formed from solutions with surfactant is not because of the order in morphology of the layer, but irreversible incorporation of the surfactant anion.

“…Hence the behavior is not limited to the polymer/electrolyte interface only because the diffusion of ions occurs inside the polymer matrix as well. To describe this authors have used distributed impedance models, [21][22][23][24] where the total impedance is often described as the sum of impedances of metal (substrate)/polymer contact, internal impedance of the polymer and the impedance offered by polymer/electrolyte interface. The solid phase in contact with the polymer provides a path for electron transport whereas the pores provide a medium for the diffusion of electrolyte and hence contributes towards ionic conduction [ Figure 9(a)].…”

Electrochemically synthesized polypyrrole (PPy) films degrade under anodic polarization in aqueous solution. PPy is irreversibly oxidized leading to subsequently to an insulating material. This article highlights the degradation behavior of electrochemically synthesized PPy films using inorganic (perchlorate, ClO 4 À ), organic (p-toluenesulfonate, pTS À ) and mixed (inorganic-organic,anions systems in aqueous solution. The PPy films were subject to overoxidation by means of anodic polarization for a certain period of time and consecutively cyclic voltammetry and electrochemical impedance spectroscopy were employed to investigate the influence of anions used during polymerization on the stability and redox activity of the polymer. The modification in the surface morphology of PPy films due to the application of anodic polarization distinctively shows the effect of degradation at polymer/electrolyte interface. The presence of organic anion in the system (PPy/pTS and PPy/mixed) has shown improved electrochemical activity and is stable to electrochemical degradation for a longer period of time than PPy/ClO 4 À .
