    Abstract

    Electropolymerization of pyrrole was carried out on tantalum as a base metal electrode. The Ta electrode retards polymerization at lower pyrrole concentrations because of the formation of insulating Ta2O5. However, at high concentrations of pyrrole, the polymerization proceeds efficiently to yield a polypyrrole (PPy) film, similar to that on a Pt electrode. The PPy film on a Ta electrode shows the same electroactivity and electric conductivity as that on a Pt electrode. Electropolymerization on Ta is accompanied by a decrease in electrode area due to the formation of the Ta2O5, the behavior of which is the only difference from that on Pt.
