应用Langmuir-Blodgett(LB)技术研究了硬脂酸和十六烷基三甲基溴化胶等金属缓蚀剂在碳钢电极上的取向。单分子膜覆盖层数及分子结构对其缓蚀作用的影响.在实验技术上实现了对缓蚀剂表面膜在分子规模上的控制,文中讨论了这两种缓蚀剂的缓蚀机理.
The langmuir-blodgett (LB) technique was used to investigate the inhibition of both stearic acid (SA) and hexadecyltrimethyl ammonium bromide (HTAB) in neutral and acidic media. The microstructure of inhibitor-formed film might be controlled on molecular scale. The relationship between the inhibition efficiency and the orientation as weel as the layer number of the LB monolayers of these inhibitors on steel electrodes was examined by electrochemical methods. Their mechanism was discussed on the ground of experimental results and calculation. It is concluded that the mechanism of SA is mainly due to the blocking effect while that of HTAB is due to the synergistic effect of Br-with the electrostatic effect of the positively charged quaternary ammonium ion of HTAB.
