| 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。

| Abstract: | 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 ℃. |
