“…As a consequence, the corrosion of mild steel in an acid medium can be inhibited. Although a few heterocyclic ring-contained compounds such as imidazole derivatives and thiophene derivatives have shown the corrosion resistance effect on mild steel in acid solution [11,12], it is still a huge challenge to seek more highly efficient corrosion inhibitors for mild steel in HCl medium, which are required to form intensified adsorption films on the mild steel surface.…”

This study employed metronidazole skeletons based on the target branched molecules (TBMs) for achieving efficient anti-corrosion of mild steel in HCl solution. In contrast, the reference linear molecules (RLMs) carrying a single metronidazole framework were also made. The excellent corrosion resistance performance of the target dendrimers for mild steel electrodes in HCl solution was demonstrated. It is shown that the TBMs displayed a superior anti-corrosion effect for mild steel over RLMs in HCl medium at 298 K (at 0.15 mol/L, TBM1, 97.70% versus RLM1, 90.89%). It is shown that the standard Gibbs free energy changes of the adsorption of the TBMs on mild steel surface are below −33 kJ/mol (TBM1, −34.58 kJ/mol), thus an enhanced adsorption film was formed.

“…DFT and molecular dynamics (MD) simulations supported the anticorrosion activity of both inhibitors. Two novel organic aromatic thiophene derivatives, 5-(thiophen-2-yl) − 1 H-tetrazole (TET) and thiophene-2-carbaldehyde oxime (OXM), were examined for the corrosion protection of mild steel in 1 M HCl [31]. The two organic inhibitors have significant resistance to the effect of time of immersion and corrosion inhibition efficiency of inhibitors increased with time.…”

Metal corrosion constitutes degradation of metals in the presence of favorable corrosive atmosphere. It worsens metal quality. The prevention of metal corrosion is so significant to save metals for their better utility. Corrosion inhibitors are widely used for the mitigation of metal corrosion. Small organic molecules as corrosion inhibitors are showed prominent corrosion inhibitive property because of their unique electron donating capacity to the metal orbitals. The bonding occurred between organic molecules and metals are main aspect to retard the corrosive environment toward metal.

“…At the current, organic inhibitor technology receives considerable interests to safeguard mild steel in acid environment due to the available and convenient performance. − The organic compounds that contain conjugated π-systems and heteroatoms such as N, O, P, and S are considered as the basic criteria to be used as the effective corrosion inhibitors. − These organic molecules are attached to a mild steel surface by adsorption, which may be processed by physisorption (such as electrostatic interaction, van der Waals force and π-empty orbitals interactions, and so on) and chemisorption (forming chemical bonds). , As a result, the adsorption of the organic inhibitors is followed by the supply of a protection barrier on mild steel that reduces the occurrence of corrosion of metals.…”

This study prepared new helmet-roled molecules (HMs) carrying metronidazole frameworks and a phenyl ring for strengthening adsorption and anticorrosion on mild steel. The adsorption of the HMs on the copper surface was understood by material simulation computation. Furthermore, the surface analysis experiments suggest that the studied molecules could be adsorbed to a mild steel surface through the chemical coordination bonding. The remarkable corrosion resistance of the HMs for mild steel in HCl was surveyed by potentiodynamic polarization and electrochemical impedance spectroscopy at 298 K. The HMs including two metronidazole skeletons displayed the stronger corrosion inhibition effect on mild steel than the HM1 bearing one single metronidazole part (the corrosion inhibition efficiency, HM3, 98.03%, HM2, 95.14%, HM1, 88.72%). The results presented in this study provided an efficient strategy to develop new clinical medicine-based corrosion inhibitors for metal in acid medium through molecular preconstruction.
