摘　　要：介绍了用溶胶-凝胶法制备纳米TiO2薄膜的过程,采用电子扫描仪和X-衍射仪表征了制得的TiO2薄膜的表面形貌和晶体结构,分析了TiO2膜亲水性的原理,通过照相法测量了水滴与膜面的接触角。结果表明,这种细致均匀、锐钛型结构的纳米TiO2薄膜具有超亲水性,将其用于汽车挡风玻璃上,有很好的防尘、防雾、防霜、自清洁的作用。A thin film of nanocrystalline TiO2 was made by sol-gel method on the automobile windshield glass. The surface morphology and crystalline structure were examined with scanning electron microscopy and X-ray diffraction,the principle of hydrophilic property of TiO2 was analyzed and contact angle between the drip and film surface was measured by the photographic process.Results showed that nanocystalline TiO2 has super hydrophilic property and can prevent from fogging, moistening and has a self-cleaning ability.
