چکیده انگلیسی
Polypyrrole (PPy) and polypyrrole-tungstate (PPy-WO42â) coatings with excellent adherence properties were electropolymerized on carbon steel using oxalic acid solutions containing pyrrole and pyrrole-tungstate, respectively. The electropolymerizations were carried out using cyclic voltammetry at the scan rate of 20Â mVÂ sâ1. Electrochemical impedance spectroscopy (EIS) was also used to evaluate the performance of two kinds of polypyrrole coatings on carbon steel surfaces under immersion in a 3.5% sodium chloride (NaCl) solution. Corrosion potentials as well as impedance data were obtained for each coating after various immersion times. Obtained results revealed that PPy-WO42â coating provided a noticeable protection enhancement against corrosion progression.
