用Sol-Gel法制备负载型纳米TiO_2薄膜的凝胶化条件

The Gelling Stipulation of Preparing Loading Nano-TiO_2 With the Mathod of Sol-Gel

纳米TiO2的制备方法归结起来有气相法和液相法。在液相法中,最常用的是硫酸法和Sol-Gel法。应用Sol-Gel法制备负载于玻片上的纳米TiO2薄膜,通过对凝胶化过程几种情况的比较,确定了在制备均匀、完整、稳定、附着力较强的纳米TiO2薄膜时凝胶化过程的控制条件,探讨了Sol-Gel反应的机理。

The gaseitymethod and the liquidmethod are the main methods of preparing nanoTiO2.We prepared the nanoTiO2 film loading on the face of glass.This method belongs to SolGel. A seires effect have been compared in defferent gelling stipulations.We elect the correct gelling stipulation to prepare the nanoTiO2 film that uniform ,integral,stable and tight.The principle of SolGel is present.
