Electrochemical preparation of polypyrrole conducting films

Cyclic voltammetry has been used to investigate the electrochemical polymerization of pyrrole on the surface of a paraffin impregnated graphite electrode (PIGE). Effect of pH and concentration of the electrolyte solution on the electrochemical deposition of polypyrrole (PPy) was studied. The structure of the deposited layers was studied using scanning electron microscope (SEM). Well–adhering black PPy films were obtained.
