正十八烷醇在HOPG上形成自组装膜的吸附特性
Adsorption Characteristics of Self-assembled 1-Octadecanol Layer on HOPG
摘要
Abstract
Long-chain alkanol,1-C18H37OH,adsorbed from solution onto highly oriented pyrolytic graphite(HOPG)and formed ordered,oriented monolayer films at room temperature in air. The formation and structure of l-octadecanol self-assembled monolayers(SAMs)on HOPG were examined using scanning tunneling microscopy(STM),contact angle measurement,and X-ray photoelectron spectroscopy (XPS).Our experimental results indicated that 1-octadecanol SAMs grew in domains,With molecules arranged either horizontally or vertically on the substrate.Moreover.the permutation means of the molecule showed relevance to the surface coverage of 1-octadecanol SAMs on the HOPG.关键词
