New triglycidyl ether triazine as a protective agent for metal: Comprehensive analysis

This study presents the synthesis and characterization of triglycidyl ether triazine (TGET), a novel epoxy resin, designed as a defensive agent for mild steel (C38) in a 1 M HCl environment. The corrosion inhibitory effectiveness of TGET was evaluated by various electrochemical methods and corroborated by surface analysis using surface and theoretical methods. The key findings demonstrate that the protection behavior of TGET rises with its concentration, achieving a maximum of 94.77 % at 10−3 mol/L, indicating a highly effective reduction in iron dissolution. Surface analysis confirmed the establishment of a defensive cover on the metal surface. The theoretical studies supported the experimental data, suggesting a strong adsorption of TGET molecules on the steel surface through chemical interaction, primarily via electron donation from the N and O atoms of the TGET to the metal surface. These results establish TGET as a highly effective corrosion inhibitor with potential applications in protecting steel structures in industrial environments characterized by acidic conditions. •The TGET demonstrates outstanding corrosion inhibition efficacy for C38 steel in HCl.•The SEM was employed to analyze the surface morphology of C38 steel.•The TGET acts as a mixed-type inhibitor.•Various classical adsorption isotherm models were employed to investigate the adsorption behavior of TGET on C38 mild steel.•The inhibition behavior of TGET has been investigated using a combination of DFT, MCS, and MD.
