有机薄膜的界面性质可以通过单层自组装现象来控制和选择，1并且随着其潜在的技术应用被认识到，对支撑自组装单分子膜（SAMs）的兴趣已经增长。2.通过对两种不同吸附质的表面浓度比（Rsam）系统变化的一系列混合自组装膜的表征，获得了关于自组装膜结构和控制其形成过程的许多信息。3· 4混合自组装膜通常通过接触角测角法、5光学椭圆偏振法6和X射线照相法的组合来表征。
The interfacial properties of organic thin films can be controlled andselected using the phenomenon of mono-layer self-assembly, 1 and interest in supported selfassembled monolayers (SAMs) has grown as their potential technical applications have been recognized. 2 Much information about the structures of SAMs and the processes that control their formation has been obtained by characterization of series of mixed SAMs in whichthe surface concentration ratio (Rsam) of two different adsorbates is systematically varied. 3· 4 Mixed SAMs have been generally characterizedby a combination of contact angle goniometry, 5 optical ellipsometry, 6 and X-ray pho-
