以钛酸丁酯为前驱液，无水乙醇为溶剂，乙酰丙酮为稳定剂，制备了 T iO 2溶胶，采用液位沉降法在清洁的玻璃衬底上镀制T iO 2薄膜。研究了添加剂聚乙二醇（1000）、p H、衬底温度对 T iO 2溶胶在玻璃基板上附着性的影响；研究了液位沉降速度、容器倾角以及溶胶附着性对T iO 2薄膜厚度的影响。考察了TiO2薄膜的表面形貌、晶相、光催化性能。结果表明，采用PEG与 Ti4＋的质量比为1，不调节pH的TiO2溶胶，在沉降速度为7 cm/min ，容器倾角为30°所制得的TiO2薄膜的光催化性能最好，光照3 h时其光催化降解率高达52.1％。

TiO2 sol was prepared with butyl titanate as precursor solution ,anhydrous ethanol as solvent ,acetylacetone as the stabilizer .TiO2 thin film was coated on a clean glass substrate by level sedimentation method .The effect of Polyethylene glycol (1 000) as the additives ,pH and the substrate temperature on the adhesion between TiO 2 sol and the glass substrate was studied . The influence of level sedimentation velocity ,container angle and the adhesion on TiO2 thin film thickness was also studied .The surface morphology ,crystal phase ,and the photocatalytic per-formance of TiO2 thin films were researched too .The results showed that when the PEG with Ti4+ mass ratio was 1 ,the pH value was not adjusted ,the settling velocity was 7 cm/min ,the container angle was 30° ,the photocatalytic properties of TiO2 thin film was the best ,which was as high as 52.1% after being lighted for 3 hours .
