用三甲氧基巯基丙基硅烷作偶联剂,通过溶剂抽提法获得单分层自组装巯基化 的玻璃。XPS和AES检测了从多层沉积到单分子层形成的过程。将所得的玻璃用于化 学镀银,XPS分析表明,溶液中新生的银通过S-Ag键的形成结合在自组装膜上,银 进一步沉积生成光亮的银镜。对沉积在巯基单分子层自组装后的玻璃上的银层进行 SEM和X射线衍射分析,结果表明用这种方法得到的镀层牢固度优于常规化学镀银所 得银层,晶体结构与常规化学镀银所得层以及金属银的晶体结构一致。

Mercaptopropyltrimethoxysilane (MPTS) was used to form self- assembly monolayers (SAMs) on glass substrates by solution extraction, which was checked with XPS and AES. These prepared glass slides were used as substrates for electroless Ag plating. XPS study showed that Ag colloids formed in the solution were successfully and firmly anchored on SAMs through Ag-S bonds. By the Ag-Ag interaction, Ag was then deposited to produce a silver-coated glass. SEM and XRD analysis illustrated that the Ag film on the SAMs-modified glass was superior in durability over that of the Ag film on the conventionally modified glass and the crystallinity of Ag film on the SAMs-modified glass was identical to that of the Ag film on the conventionally modified glass and pure Ag.
