利用超分子自组装方法在普通玻璃表面制备了仿贝壳有机-无机复合纳米薄膜 。采用X射线衍射仪、傅立叶红外光谱仪、X射线光电子能谱仪及透射电子显微镜等 对薄膜结构进行了表征。用动-静摩擦系数测定仪初步考察了其摩擦行为。结果表 明，这种薄膜具有机-无机有序交替的层状纳米复合结构，其聚合前的层间距为4. 20 nm, 聚合后的层间距为3.91 nm。聚合后的仿贝壳自组装纳米复合薄膜具有良好 的减摩性能。

The composite thin film of TiO_2/organic compound was prepared on glass substrate using supermolecular self-assembly method. The structure of the thin film was characterized by means of Fourier transform infrared spectrometry, X-ray photoelectron spectrometry, X- ray diffraction, and transmission electron microscopy. THe friction behavior of the composite thin film in sliding against AISI-52100 steel was investigated with a DF-PM friction coefficient measurement apparatus. The results indicate that the thin film is composed of organic and inorganic layers in alternately orderly arrangement. The distance between the organic layer and inorganic layer is 4.20 nm before polymerization and 3.91 nm after polymerization. The friction coefficient of the film sliding against steel is 0.1, which is much lower than 0.87 - the friction coefficient for glass sliding against the steel. Moreover, the polymerized film has longer antiwear life than the unpolymerized one.
