利用纳米ZnO对纳米TiO_2表面进行修饰,采用分步沉淀法制备物质的量比为10:1,10:2,10:3,10:4,10:5,10:6和10:7的TiO_2/ZnO复合粉体,比较不同物质的量比制备的纳米复合物的结构与性能差异,并分析其对紫外-可见光下的光催化活性、抗紫外线及自清洁性能的影响.结果表明:当物质的量比为10:3时,紫外-可见漫反射光吸收达最佳值,光催化效果增强;将其整理到织物上后,织物抗紫外线性能UPF值达到50以上,且自清洁效果较好. The surface of nano-TiO 2 was modified by nano-ZnO, and TiO 2 was prepared by the step-precipitation method in the ratio of 10: 1,10: 2,10: 3,10: 4,10: 5,10: 6 and 10: 7 / ZnO composite powders were prepared and the differences in the structures and properties of the prepared nanocomposites were compared and the effects on the photocatalytic activity, anti-UV and self-cleaning properties under UV-Vis were analyzed. The results showed that when the mass , The UV-visible diffuse reflectance reached the best value and the photocatalytic activity was enhanced. After finishing the fabric on the fabric, the UPF value of the fabric reached above 50 and the self-cleaning effect was better .
