Abstract Self-assembled monolayers (SAMs) is an ordered molecular assembled system through adsorbing surfactant matter on the solid surface. The factors that can influence the wettability of SAMs are shown as the following: physical and chemical properties of molecular end-group; orientation of molecular end-group; thickness of SAMs; van der Walls forces of the metal substrate; properties of the substrate; solution temperature and so on. . The opportunities for the studies on SAMs wettability are recommended.
Key words Self-assembled monolayers (SAMs), Wettability, Progress

摘要 自组装单分子膜(SAMs)是利用活性分子通过化学键自发吸附在异相界面上形成的稳定和有序的超分子体系。SAMs在设计制造新型功能材料和分子器件的组装方面都具有极其广阔的应用前景。应用SAMs的关键是对其表面性质及其影响因素的透析,本文就SAMs润湿性的研究发展作了简单介绍,归纳了分子端基的理化性质、分子端基取向、金属基质van der Waals力、基质性质和环境温度等因素对自组装单分子膜润湿性的影响,并对SAMs润湿性的研究进行了展望。
