Abstract
In this paper, polypyrrole (PPy) conductive polymers were created in the presence of ferric chloride (FeCl3) and ammonium peroxodisulfate (APS) oxidants. Sodium molybdate (Na2MoO4) is used for the PPy corrosion inhibitory effect in NaCl solution. According to the electrochemical impedance spectroscopy (EIS) results, the corrosion resistance of steel plates subjected to the Na2MoO4 containing solution with different ratios of PPy-FeCl3 and PPy-APS was significantly improved, revealing that the barrier properties of the PPy film have drastically improved in the presence of Na2MoO4. The polarization test results revealed noticeable corrosion rate decrement with the incorporation of molybdate to the PPy-FeCl3-containing solution.
