The Use of Conducting Polyaniline as Corrosion Inhib

Sulfonated chitosan (S-CTS) doped polyaniline (PANI) was synthesized by template-free method
successfully, and it is reported as corrosion inhibitor for the first time. The corrosion inhibition
property of PANI was demonstrated for mild steel in acidic environment using weight loss test, Tafel
polarization, electrochemical impedance spectroscopy (EIS), scanning electronic microscope (SEM)
and adsorption isotherm.
