| 摘 要： | 利用分子自组装技术，在单晶硅表面制备了MPTS MPTES /稀土复合自组装膜.利用接触角测定仪、原子力显微镜和X射线光电子能谱仪分析表征了薄膜的组成和结构；采用DF-PM型静-动摩擦系数精密测定仪评价了薄膜的摩擦磨损性能.研究结果表明：稀土元素可以组装到氧化后的硅烷化表面而形成MPTS-MPTES /稀土自组装复合薄膜.在较低载荷下，薄膜不但摩擦系数较低，同时也表现出良好的耐磨性和摩擦稳定性，显示了其在微型机械表面改性的潜在应用前景.

| Abstract: | The composite film of nanometer rare-earth/silicon coupling reagent MPTS-MPTES was prepared on the hydroxylated single-crystal silicon substrate by a self-assembling process from specially formulated solution.The resultant composite film was characterized by means of atomic force microscope(AFM) and X-ray photoelectron spectroscopy(XPS).The contact angles of distilled water on the silane SAMs and the composite film were measured to compare the surface states.The tribological properties of the films sliding ... |
