Synthesis, Characterization and Corrosion Behavior of Isomers of Conducting Poly?Toluidine on Mild Steel in Acid Medium

G.Madhusudhana | R. Jaya Santhi

Abstract: Isomers of Poly-toluidine have been synthesized using chemical oxidation method at 0C using potassium dichromate as oxidant and hydrochloric acid as dopant. The synthesized polymers were characterized using IR, UV, TGA, DTA, XRD and SEM. The AC conductivity of POT, PMT, and PPT showed that they were semiconducting in nature. The corrosion behavior of the polymer on mild steel in acidic medium was studied by using electrochemical techniques. The studies showed that the inhibition increased with increase in concentration and reaches an optimum efficiency. The study further revealed that the inhibition efficiency followed the order PMT>PPT>POT. Polarization studies indicated that these three polymers act as mixed type corrosion inhibitors and EIS study showed that the dominant coating mechanism follows kinetic controlled corrosion mechanism.
