Abstract

Conductive polypyrrole was synthesized with hydrogen peroxide (H₂O₂) as the oxidant. To promote the polymerization of pyrrole, UV radiation was employed. The effects of UV radiation on the preparation of polypyrrole were investigated. The polymerization of pyrrole was conducted with the H₂O₂ concentration in the range of 0.12-0.96 M and the H₂SO₄ concentration in the range of 6.8 × 10^-4-0.19 M. The structure characterization indicated that the product polypyrrole was overoxidized partly depending on the concentrations of H₂SO₄ and H₂O₂. The increase in H₂O₂ concentration led to a slight increase in the oxidation and overoxidation of polypyrrole, simultaneously. However, the increase in H₂SO₄ concentration effectively suppressed the overoxidation of polypyrrole. The morphology, conductivity and thermal stability of the products were also characterized.
