Abstract
This manuscript synthesized successfully two efficient imidazole-Schiff derivatives (FMIX and MIX), and confirmed the structural rationality through infrared spectroscopy (IR), nuclear magnetic resonance(NMR) and elemental analysis, and the corrosion inhibition performance and mechanism in 1.0 mol/L HCl were investigated. The weight loss experiment showed that at 2.0 mmol/L and the corrosion inhibition efficiency of FMIX and MIX were 97.39 % and 98.52 %, respectively, indicating that this corrosion inhibitor has excellent corrosion inhibition performance. The open circuit potential (OCP) and potentiodynamic polarization curve (Tafel) indicated that FMIX and MIX belong to cathodic corrosion inhibitors. Electrochemical impedance spectroscopy (EIS) shown that FMIX and MIX increased the film resistance and charge transfer resistance in the corrosion solution, and adsorbed on the surface of Q235 to form a stable protective film. XPS, EDS, and IR tests have shown that FMIX and MIX could adsorb on the surface of Q235 to form a stable protective film, thereby inhibiting the occurrence of corrosion. Density functional theory (DFT) and molecular dynamics simulation (MD) have also confirmed at the molecular level that FMIX and MIX could spontaneously adsorb on the surface of Q235 and form a stable protective film.
