EFFECT OF MOS2 DOPED CONDUCTING POLYMERS TO CORROSION OF MILD STEEL

Year 2019, Volume: 2 Issue: 2, 133 - 136, 15.11.2019

Abstract

One of the most common ways
of protecting metals from corrosion is to form a film on metal surfaces or to
coat them with suitable materials. Thus, metals are protected from corrosive
components in their environment. However, in the case of openings at the micro
level that may occur in the formation of the coating or in case of scratches
and similar openings that may occur after the coating, water and air will reach
the metal surface and initiate corrosion.
 In
this study, the effect of polypyrrole (PPy), polyaniline (PANI) and MoS2 doped
PPy and PANI coatings on the corrosion rate of steel was investigated.
Corrosion resistance of these coatings was determined by measuring corrosion
rates by Tafel Polarization method in 0.1 M NaCl medium. Because of the
experiments, it was determined that these homogeneous and adhering coatings
were effective against corrosion. The best protection against corrosion was
found as 96.7%, 89.0%, 69.5% and 45.2% for PPy + MoS2, PPy, PANI + MoS2 and
PANI coatings, respectively. MoS2 additive yielded positive results for both
coatings. Better protection of PPy than PANI can be explained by the fact that
the oxidation potential of pyrrole (0.6 V) is lower than the aniline oxidation
potential.
