“…60 o (Figure 5b). Higher  values of PABA and PABA-ORG polymer film coated SS electrodes attributed to limited corrosive products diffusion process taking place through the pores of the coating and the formation of new oxide films towards the underlying SS surface at metal/solution interface (14)(15)(16)(17)(18). In Figure 5c, the incremental Rp value of depressed semicircle obtained polymer-coated both electrodes at the high frequency indicated the growth of the passive films consisted of nickel and chromium oxides, metal/polymer interface.…”

“…Warburg impedance assumes the diffusion resistance consisting of corrosion types of the substrate because of being at approx. 45 o of angle, in phase angle, ()-log f plots (14)(15)(16)(17)(18). The observation of the linear portion at the lowfrequency district showed that the coating had active barrier property.…”

In this work, we obtained the anticorrosive properties of polymer films (SS/PABA and SS/PABA-ORG) synthesized on stainless steel surface by adding an organic substance to aniline derived oaminobenzyl alcohol monomer synthesis medium. Firstly, we prepared the polymer coating bath by dissolving 0.15 M o-aminobenzyl alcohol monomer in the electrolyte solvent containing acetonitrile and 0.15 M LiClO4. From this bath, poly (o-aminobenzyl alcohol) (PABA) film was synthesized in 30 segments by cyclic voltammetry (CV) technique at a scanning rate of 50 mV/s at a potential range of-0.20/1.80 V on the AISI 316 (SS) working electrode in contrast to the platinum electrode. For the synthesis of organic structure doped polymer film (PABA-ORG), we repeated the same synthesis process by dissolving C21H27NO2(k) (ORG) at low concentration in the same bath. We investigated the corrosion performances of bare SS, SS/PABA, and SS/PABA-ORG substrates, using open circuit potential-time, anodic polarization, and AC impedance techniques in the solution of corrosion study. As a result, we observed that the organic additive added to the synthesis medium caused changes in the synthesis behavior of PABA. Corrosion performance tests showed that PABA and PABA-ORG films increased the corrosion protection performance of the SS electrode, and we observed a reduction of the corrosion rate of the SS electrode.

Electrosynthesis of poly(o‐anisidine) (POA) homopolymer and poly(o‐anisidine)‐TiO2 (POA‐TiO2) nanocomposite were carried out on ZnNi plated carbon steel (CS/ZnNi). The synthesis was achieved cyclic voltammetry technique in 0.2 M sodium oxalate solution containing 0.1 M o‐anisidine and o‐anisidine + 0.2 gL−1 TiO2 nanoparticles for POA and POA‐TiO2, respectively. The POA and POA‐TiO2 nanocomposite were characterized by scanning electron microscopy (SEM), energy dispersion x‐ray analysis (EDX), electrochemical impedance spectroscopy, linear sweep voltammetry, open circuit potential‐time and potentiodynamic polarization techniques. Electrochemical impedance spectroscopy, open circuit potential‐time (Eocp‐t) and potentiodynamic polarization tests were done in 3.5% NaCl solution. Potentiodynamic polarization curves showed that a strong decrease of corrosion current for POA‐TiO2 coated CS/ZnNi (CS/ZnNi/POA‐TiO2) electrode when compared to the POA coated CS/ZnNi (CS/ZnNi/POA) and CS/ZnNi electrodes. Electrochemical impedance spectroscopy results indicated that polarization resistance (Rp) of the CS/ZnNi/POA‐TiO2 electrode was higher than the other electrodes. These results revealed that TiO2 nanoparticles increased the anticorrosive property of the POA film.

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 À 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 terpol-ymer 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 À 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 À 1 TiO 2 . These results showed that the amount of TiO 2 affects the anticorrosive properties of the synthesized nanocomposite.
