Poly(aniline‐co‐pyrrole‐co‐N‐methylpyrrole) (P(ANI‐co‐PY‐co‐NMP)) terpolymer film was synthesized in 0.30 M oxalic acid solutions containing 0.05 M aniline +0.05 M pyrrole +0.05 M N‐methylpyrrole. Poly(aniline‐co‐pyrrole‐co‐N‐methylpyrrole)‐TiO 2 nanocomposites were synthesized in 0.30 M oxalic acid solutions containing 0.05 M aniline +0.05 M pyrrole+0.05 M N‐methylpyrrole+0.1/0.4/1.0 gL −1 TiO 2 . Electrochemical syntheses were performed on the carbon steel (CS) elctrode using cyclic voltammetry technique. The terpolymer and nanocomposites were characterized by SEM, EDX, electrochemical impedance spectroscopy (EIS), open circuit potential‐time and anodic polarization techniques. Nanocomposite structures were observed after the addition of TiO 2 nanoparticles into terpolymer films and these results was verified via EDX analysis. The results driven by EIS and anodic polarization suggest that, terpolymer and nanocomposite coated electrodes have been shown to have a protective effect against the corrosion of the CS electrode. The nanocomposite coated electrode synthesized in an environment containing 0.4 gL −1 TiO 2 was found to have higher corrosion resistance in comparison to uncoated electrode, terpolymer coated electrode and electrodes coated with nanocomposites that is synthesized in environments containing 0.1/1.0 gL −1 TiO 2 . These results showed that the amount of TiO 2 affects the anticorrosive properties of the synthesized nanocomposite.
