LB技术制备SnO_2_TiO_2无机交替纳米薄膜

Preparation of SnO_2-TiO_2 Alternate Nanoparticulate Film by LB Technique

采用LB技术将SnO2纳米粒子和TiO2纳米粒子组装进花生酸的交替多层膜,通过热处理除去膜中的有机成分后,采用红外光谱、紫外可见光谱、X鄄光电子能谱、低角X鄄射线衍射、原子力显微镜以及扫描电子显微镜等手段对处理后的膜进行了形貌、组成和结构表征,表明制得的是SnO2纳米粒子鄄TiO2纳米粒子无机鄄无机交替的均匀的纳米薄膜。

By LB technique, the arachidic acid-doped SnO2 and TiO2 nanoparticulate monolayers were prepared on the water surface and then were transferred on to solid substrates such as silicon, mica, quartz and so on alternately. The as-deposited alternate LB film was treated at high temperature and then was characterized by Fourier transform infrared spectroscopy, UV-Visible spectroscopy, low angle X-ray diffraction, X-ray photoelectron spectroscopy, SEM and AFM. The results indicate that SnO2 nanoparticles and TiO2 nanoparticles formed a pure inorgame periodic nanoparticulate film.
