摘要：The adsorption potential energy curves of imidazoline compounds and Zn atom were calculated by quantum chemistry method.The adsorption energy, imidazoline ring, the coordination bond length between nitrogen atom and Zn atom, the double atom interaction energy and the overlapping population number were obtained.The results show that the introduction of power-providing groups or substituted aromatics into imidazoline ring can enhance the chemical adsorption force between N and Zn. The calculation results can provide a useful theoretical basis for the design of corrosion inhibitors with better performance.
