| 摘 要： | 采用银在水溶液表面形成C18SH自组装膜(SAMs)的工艺，在银表面得到致密、平整，表现出明显疏水性的SAMs。EMPA和XPS测试表明，表面活性剂分别作为C18SH的分散剂，自组装过程中起到传输作用，本身不参与成膜，但影响SAMs的厚度和倾斜角。银试样表面的Ag2O在成膜过程中被硫醇中的H-S键还原为Ag，同时有Ag-S-C18H37键的形态形成。

| Abstract: | By use of octadecanethiol adsorption onto silver in aqueous micellar solution, self-assembled monolayers (SAMs), which were dense, smooth and hydrophobic, were obtained. EMPA and XPS tests show that the surfactants including CTAB, TX-100, PLE and PE6400, as the dispersants of octadecanethiol, play a role of transfer during the self-assembling process; they do not take part in monolayer formation themselves but they can influence the thickness and tilt angle of SAMs. Ag2O on the surface is reduced by H-S bond of the thiol, and Ag-S-C18H37 is formed at the same time. |
