不同链长烷基硫醇自组装膜对银的防变色作用
Tarnish Protection for Silver Using Self-assembled Monolayers of Alkanethiols with Different Chain Lengths
摘 要
将不同链长的烷基硫醇溶于乙醇，在银表面制备自组装膜。采用接触角测试、电化学试验、加速变色试验和X射线光电子能谱（XPS）等方法来表征自组装膜的性能。结果表明：十二烷基硫醇（DT）、十六烷基硫醇（HDT）和十八烷基硫醇（ODT）都可以在银表面形成疏水性的自组装膜，对基体腐蚀起到良好的保护作用；ODT自组装膜的致密性最好，而HDT自组装膜的防变色效果最好。

Abstract
Self-assembled monolayers (SAMs) of three alkanethiols on silver surface were prepared in ethanol solution. The properties of SAMs were investigated by contact angle measurement, electrochemical testing, accelerated tarnishing test and X-ray photoelectron spectroscopy (XPS). The results indicate that the hydrophobic SAMs of dodecanethiol (DT), hexa decanethiol (HDT) and octa decanethiol (ODT) were able to form on the surface of silver. And the SAMs had good protection against corrosion for the substrate. The ODT SAM had the best compactness, while the HDT SAM had the best anti-tarnishing effect.
