ELECTROPOLYMERIZATION OF PYRROLE IN THE PRESENCE OF TETRACHLOROFERRATE ANION

The influence of the addition of tetraethylammonium tetrachloroferrate Et4NFeCl4 (TEATCF) on the electropolymerization (EP) of pyrrole and t he electrochemical properties of polypyrrole (PP) films obtained poten tiodynamically or galvanostatically is studied using cyclic voltammetr y and preparative electrolysis. Introduction of TEATCF into the electr olyte at the stage of pyrrole EP is shown to accelerate the process an d lead to an increase in the roughness on the surface of the PP films that are formed. The addition of TEATCF allows one to obtain conductin g films under galvanostatic conditions and without degradation of the polymeric material, even at elevated current densities.
