| 摘 要： | 本文采用十二烷基磺酸钠(SDS)作模板并以明胶作稳定剂，在空气-水的界面上组装TiO2薄膜。结果表明，采用明胶稳定的薄膜具有良好的机械强度。采用X射线角度扫描技术(AD)原位检测薄膜的结构，并用X射线宽角衍射(WAXS)和小角衍射(SAXS)技术对经后续处理的TiO2薄膜结构进行了表征。研究发现，明胶的加入可显著降低薄膜中TiO2颗粒细度；经洗涤后，此复合薄膜材料可转换成纯层状的TiO2薄膜。分析了明胶稳定TiO

| Abstract: | Gelatin can be effectively used to stabilize the self-assembly of titania-based film at the air-water interface by using sodium dodecyl sulfate (SDS) as template. Angle-dispersive reflectivity (AD) X-ray reflection and other X-ray reflection methods have been employed to characterize the preparation process and structure of the titania films. In addition, the mechanism of layered titania dispersion in gelatin was discussed. The growth kinetics of the film was formulated and it has been suggested that a simple result is suitable for the self-assembly of titania-based film in the presence of gelatin. |
