| 摘 要： | 稳定性是表征溶胶质量的重要指标,通过溶胶的粘度可以直接表征.以钛酸四丁酯,无水乙醇,乙酰丙酮(Acac),冰乙酸为原料,采用溶胶-凝胶法制备纳米TiO_2薄膜,跟踪测量溶胶粘度随时间的变化规律,粘度合适且长期稳定的溶胶适合于制备高质量的薄膜.讨论溶胶各组分的配比与溶胶稳定性的关系.结果表明,影响胶化时间和溶胶粘度的主要因素为去离子水、乙酰丙酮、冰乙酸和乙醇的用量;制备粘度合适且长期稳定的溶胶最佳配比(摩尔比)为钛酸四丁酯:无水乙醇:水:乙酰丙酮:冰乙酸=1:30:3:1.5:1.5.利用SEM、UV-vis、XRD等对薄膜样品的结构、形貌与性能进行表征.

| Abstract: | As the key index of the sol quality,the stability can be characterized by the viscosity of sols. Nano TiO2 thin film was prepared by sol-gol method from tetrabutyl titanate,absolute alcohol,acetylacetone and glacial acetic acid and the viscosity change of sols were tracked and measured. The sols possessing suitable and stabilizing viscosity were fit to prepare the high-quality films. The relationship between ratios of each components and the stability of sols were discussed. The results indicated that the p... |
