A new polymer was synthesized using N-methyl aniline and 2-Propyl pentatonic acid on 304- stainless steel by electrochemically. An adherent polymer film was obtained by cyclic voltammetry method. The PANi-2PPA coated polymer was investigated against corrosion inhibitive nature in 0.5 M sulphuric acid solutions by Potentiodynamic polarization technique and electrochemical impedance spectroscopy. Corrosion current, corrosion current density, anode and cathode tafel slopes, charge transfer resistance, double layer capacitance parameters were observed in the electrochemical corrosion investigation methods. The maximum inhibition efficiency was achieved by potentiodyanamic polarization method.
