Abstract
In this work, it was studied to obtain 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 o-aminobenzyl alcohol monomer synthesis medium. Firstly, polymer coating bath was prepared by dissolving 0.15 M o -aminobenzyl alcohol monomer in electrolyte solvent containing acetonitrile and 0.15 M LiClO4. From this bath, poly (o-aminobenzyl alcohol) (PABA) film was synthesized in 30 segments by a 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), the same synthesis process was repeated by dissolving C21H27NO2(k) (ORG) at low concentration in the same bath. Corrosion performances of bare SS, SS/PABA and SS/PABA-ORG substrates were investigated using open circuit potential – time, anodic polarization and AC impedance techniques in corrosive solution. As a result of the study, it was 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 SS electrode and it was observed to reduce the corrosion rate of SS electrode.
