摘　　要：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、紫外-可见吸收光谱仪、透射电子显微镜对薄膜结构进行了表征.结果表明这种薄膜具有有机-无机有序交替的层状纳米复合结构,聚合前层间距为4.20nm,聚合后层间距为3.91nm.无机层由TiO2纳米微粒构成.The TiO2/organic composite thin film was prepared using supermolecular self-assembly method on glass substrate. The structure of the thin film was characterized by FT-IR, UV-Vis, XRD and TEM techniques. The results indicated that the thin film was composed of alternative orderly appeared organic and inorganic layers. The distance between organic layer and inorganic layer was 4. 20 nm before polymerization and 3. 91 nm after polymerization, respectively. The inorganic layers were composed of TiO2 nanoparticles.
