INFLUENCE OF GRAPHENE OXIDE ON THE CORROSION INHIBITION EFFECT OF HYDROTALCITE LOADED WITH 2-BENZOTHIAZOLYTHIO-SUCCINIC ACID
Keywords:hydrotalcite, 2-benzothiazolylthio-succinic acid, graphene oxide, solvent free epoxy coating, corrosion protection
Hydrotalcite intercalated with 2-benzothiazolylthio-succinic acid and graphene oxide (HT-BTSA/GO) was synthesized by co-precipitation method. Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) were used to characterize obtained HT-BTSA/GO. The release of BTSA from HT-BTSA/GO in NaCl solution at different concentrations was investigated by UV-Vis spectroscopy. HT-BTSA/GO was incorporated in solvent free epoxy coatings at concentration of 1 wt% and the corrosion protection of these coatings on carbon steel were examined by salt spray test and adhesion measurement. It was shown that GO and BTSA were intercalated in hydrotalcite structure and BTSA content was about 19.7 wt%. The release of BTSA from HT-BTSA/GO depended on chloride ion concentrations. After 72 h immersion in 0.1 M and 0.5 M NaCl solutions, the BTSA release were about 19.3 % and 61.0 % respectively. The presence of HT-BTSA/GO improved the corrosion resistance and adhesion of solvent free epoxy coatings. The corrosion protection performance of coatings containing HT-BTSA/GO was higher in comparison to the coating containing HT-BTSA.
