| 摘 要： | 采用分子自组装技术，在单晶硅表面制备3-巯丙基三甲氧基硅烷(MPTS)、3-甲基丙烯酰氧丙基三甲氧基硅烷(MPTES)薄膜以及MPTS/MPTES复合自组装薄膜，利用原子力显微镜（AFM）、X射线光电子能谱仪（XPS）及接触角测定仪对MPTS/MPTES复合薄膜的结构进行分析，并采用DF PM型动/静摩擦系数精密测定仪评价其摩擦磨损性能.结果表明，与MPTS薄膜和MPTES薄膜相比，MPTS/MPTES复合薄膜具有优异的疏水性和摩擦磨损性能，其原因在于MPTS/MPTES复合薄膜的分子体积较大并具有可移动性和特殊的柔韧性，其基底附近呈现出类似于固体紧密排列的结构并具有一定的刚性和承载能力.

| Abstract: | MPTS/MPTES self-assembled film was fabricated on single-crystal silicon substrates by molecular self-assembly process.Atomic force microscope(AFM),X-ray photoelectron spectrometry(XPS) and contact angle measurer were used to characterize the thin films.The tribological properties of the films sliding against GCr15 steel ball were evaluated on a DF-PM reciprocating friction and wear tester.The(results) show that the MPTS/MPTES film has excellent hydrophobic and friction and wear behavior properties compared ... |
