中文摘要：

对长碳链硅烷在玻璃片表面自组装形成单分子层膜进行研究。以甲苯为溶剂,使辛烷基三乙氧基硅烷（OTES）、十二烷基三甲氧基硅烷（DTMS）、3-胺丙基三乙氧基硅烷（APTES）和十八烷基三氯硅烷（OTS）在玻璃表面进行生长,考察反应时间、反应浓度和可水解基团对自组装单分子层膜的影响。用接触角仪和全反射红外光谱仪（FT-IR）对单分子膜进行表征。结果表明：带有—Cl水解基团的OTS最易生长,而带有乙氧基离去基团的OTES比带有甲氧基的DTMS容易反应。在24℃时,1 mmol/L OTES反应20 min自组装单分子层膜生长很好,并且表面比较规整均一。

英文摘要：

A series of silanes were explored on their ability to form self-assembled monolayers（SAMs） on glass,including octadecyltrichlorosilane（OTS）,dodecyltrimethoxysilane（DTMS）,octyltriethoxysilane（OTES）,and 3-aminopropyltriethoxy silane（APTES）.The SAMs were allowed to grow in toluene.The effects on growth time,solution concentration,and hydrolysable groups were analyzed.SAMs were characterized by contact angle goniometry and Fourier transform infrared spectroscopy（FT-IR）.Results showed that OTS the fastest grew,OTES grew faster than DTMS due to their different hydrolysable groups.For OTES,1 mmol/L solution yielded relatively well-ordered SAM in 20 min at 24 ℃.
