研究了正十八烷醇在高定向热解石墨(HOPG)上形成自组装膜的吸附特性,正十八烷醇在室温下从溶液中吸附至HOPG上形成整齐定向排列的单层自组装膜.通过扫描隧道显微镜(STM)、接触角测量和X射线光电子能谱(XPS)分析了正十八烷醇单层自组装膜在HOPG上的结构.实验结果表明,正十八烷醇自组装膜在基底上成平铺或直立形态,由于分子在基底上覆盖程度的不同,会导致它在基底上排列的方式有所不同. The adsorption behavior of n-octadecanol on self-assembled films formed on highly oriented pyrolytic graphite (HOPG) was studied. N-Octadecyl alcohol was adsorbed onto HOPG from solution at room temperature to form a monolayer self- The structure of the monolayer self-assembled n-octadecanol on HOPG was analyzed by scanning tunneling microscope (STM), contact angle measurement and X-ray photoelectron spectroscopy (XPS) .The experimental results showed that n-octadecanol self-assembled The film is tiled or erect on the substrate, and the way in which the molecules line up on the substrate varies due to the degree of molecular coverage on the substrate.
