Abstract

In this study, inhibition effect of a trifunctional epoxy resin (designated as TGEAP) on carbon steel (CS) corrosion is evaluated using different techniques. Electrochemical demonstrations showed that TGEAP showed optimum efficiency of 90 % at 10⁻³M concentration. Mixed- and interface-type behaviour of TGEAP was confirmed by polarization and electrochemical impedance spectroscopic (EIS) studies, respectively. Effect of temperature on anticorrosive effect of TGEAP was also studied and results showed that decrease in the protection efficiency was observed with rise in the temperature. Computational modelings analyses were adopted to describe the interactions between metallic surface and TGEAP molecules. Results showed that TGEAP interacts through donor-acceptor interactions and acquires nearly flat orientation on metallic surface.
