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 C₂₁H₂₇NO_2(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.
