摘要
在铜合金表面成功组装了两种不同端基的分子自组装膜,通过电化学分析方法测试了组装后的试样在天然海水中的耐腐蚀性能,并通过能谱、红外和接触角分析了材料表面成分及性能,结果显示,随组装分子浓度的增加,腐蚀速率降低,当自组装分子浓度达到10mM时,分子膜的腐蚀抑制效率都能达到90%以上。热力学分析结果表明自组装分子的吸附过程遵循Langmuir吸附等温式。
The self-assembled monolayers(SAMs) of 11-mercaptoundecan-1-ol on B10 surface were prepared and the corrosion inhibition action in natural seawater was investigated by potentiodynamic polarization,electrochemical impedance spectroscopy and scanning electronic microscope.With the increasing of concentration the inhibition efficiency increases.At the concentration of 10 mM,SAMs act as excellent corrosion inhibitors with inhibition efficiencies about 90%.Adsorption of the SAMs followed Langmuir adsorption isotherm.
