| 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.

| Abstract: | 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 1mol/LHCl solution was observed by metallography microscope. The results indicated that self-assmbled monolayer has a corrosion inhibition performance on copper. The self-assembled monolayer inhibition efficiency reached 85.3% in 1mol/LHCl solution. The corrosion inhibition efficiency was related with concentration. The high concentration of self-assembled monolayer on copper corrosion inhibition was significantly better than the low. |
