Abstract
A voltammetric study of a Pt electrode in pyrrole-polyvinylsulphonate (PVS) aqueous solutions, showing different concentrations of the polyelectrolyte was performed. Potential range for the composite (polypyrrole-PVS) reversible redox behaviour for its passivation, and for the water discharge were studied by voltammetry. The electropolymerization of composite films of polypyrrole-polyvinyl sulphonate was performed under a constant potential of 800 mV from aqueous solutions. Parallel kinetics through ex-situ microgravimetric determination of the dry film weights, through electrical charges consumed during the electropolymerization, and through electrical charge consumed during the electropolymerization, and through electrical charge stored in the electroactive films were obtained. The polymerization mechanism change along the polymerization time, giving low current efficiencies and low storage of charge per gram of polymer.
