纳米TiO2薄膜的制备及自清洁性能研究

通过溶胶一凝胶法在普通钠钙玻璃表面制备均匀透明的纳米TiO2自清洁薄膜。探讨了薄膜制备的工艺条件，并利用X射线衍射（XRD）、紫外分光光度计对薄膜的晶型、晶粒大小和透光率进行了表征，研究了在紫外光照射下薄膜的光催化性能及亲水性能。结果表明，制得的TiO2薄膜具有较强的自清洁性能。

Preparation of Nano-TiO2 Film and Research on Its Self-cleaning Activity

The uniform,transparent nano-TiO2 films were prepared by sol-gel method on common soda lime glass.The technique for producing TiO2 films was discussed,and the structure,grain size and the film transmittance were characterized by X-ray diffraction(XRD) and ultraviolet spectrophotometer.The hydrophilicity and photocatalytic activity of the films were studied under the UV light.The results indicate that TiO2 films made have higher self-cleaning activity.
