摘要
合成了双水杨醛缩邻苯二胺席夫碱,在铜片表面制备了席夫碱的自组装分子膜。利用电化学工作站分析了席夫碱自组装膜对铜片的缓蚀效果,利用金相显微镜观察1 mol/L HCl腐蚀后铜片表面形貌。结果表明:双水杨醛缩邻苯二胺席夫碱对铜有一定的缓蚀效果,自组装膜在1 mol/L的盐酸溶液中缓蚀效率达到85.3%。自组装膜的缓蚀效率与浓度有关,浓度高的自组装膜对铜片的缓蚀作用明显高于低浓度的自组装膜。
N,N＇-bis（salicylidene）-o-phenylenediamine schiff base was synthesized,and the self-assembled monolayer of schiff base was formed on copper surface.Electrochemical workstation was used to analyze the schiff base films for the copper＇s corrosion inhibition performance.The corrosion of copper in 1 mol/L HCl solution was observed by metallography microscope.The results indicate that self-assmbled monolayer has a corrosion inhibition performance on copper.The self-assembled monolayer inhibition efficiency reaches 85.3% in 1 mol/L HCl solution.The corrosion inhibition efficiency is related with concentration.The high concentration of self-assembled monolayer on copper corrosion inhibition is significantly better than the low.
