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 the electrochemical properties of polypyrrole (PP) films obtained potentiodynamically or galvanostatically is studied using cyclic voltammetry and preparative electrolysis. Introduction of TEATCF into the electrolyte at the stage of pyrrole EP is shown to accelerate the process and 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 conducting films under galvanostatic conditions and without degradation of the polymeric material, even at elevated current densities.
