摘要：

In situ electropolymerization leading to polythiophene coating has been found to be a new option for providing corrosion protection to mild steel surface. The polythiophene coating thus coated has been diagnosed through polarization and AC impedance analysis, which has demonstrated the passivation. role of conducting polythiophene coating. The determination of volume fraction, water uptake and delamination area have been used to further support the corrosion protection of conducting polythiophene coating. (C) 2001 Elsevier Science B.V.
