In this work, the corrosion inhibition effectiveness of semi natural lignin polymers, lignin-acrylamide and lignin-acrylic acid, in HCl solution was investigated by means of weight loss, polarization, electrochemical impedance, atomic force microscope (AFM) and scanning electron microscope (SEM) analyses. The results showed that the inhibition effectiveness of lignin-acyclic acid (AA) was better than that of lignin–acrylamide (AM), because the corrosion inhibition efficiency and adsorption capacity of lignin-AA on carbon steel surface were more significant than those of lignin-AM. AFM and SEM analyses showed that the surface of carbon steel was insignificantly affected in HCl solution containing lignin-AA. The mechanism of inhibition effectiveness of lignin-AA and lignin-AM in HCl solution was also verified by molecular dynamics (MD) simulations.

在这项工作中，通过失重，极化，电化学阻抗，原子力显微镜（AFM）和扫描电子显微镜（ SEM）分析。结果表明，木质素-无环酸（AA）的抑制效果优于木质素-丙烯酰胺（AM），因为木质素-AA在碳钢表面的腐蚀抑制效率和吸附能力比木质素更显着。 -是。原子力显微镜和扫描电镜分析表明，在含有木质素-AA的HCl溶液中，碳钢的表面受到的影响很小。木质素-AA和木质素-AM在HCl溶液中的抑制作用机理也通过分子动力学（MD）模拟得到了验证。
