在酸催化体系中以正硅酸乙酯(TEOS)和纳米锐钛矿型二氧化钛粉末为SIO2-TIO2复合溶胶原料,采用提拉法在高硼硅玻璃基片表面制备出具有增透和自清洁功能的薄膜。研究了制备工艺对薄膜增透和光致超亲水性能的影响。制备的样品在400~800 nM波段,光线垂直入射时,透射率增加3%,紫外光照射一定时间后,样品对水接触角不超过5°,具有光致超亲水作用。The self-cleaning glass antireflection film was prepared on the surface of high borosilicate glass substrate by using TEOS and nanometer anatase type of titanium dioxide powder as sol-gel SiO2-TiO2 composite raw materials and using Czochralski method.The effect of preparing technique on antireflection and photoinduced super hydrophilicity properties was investigated.The experiments show that the light transmittance of prepared sample increased about 3% at wavelength between 400nm and 800nm under light vertical incidence.After UV irradiation for a certain time,the water contact angle was ≤5° which exhibited the characteristic of photoinduced super hydrophilicity.福建省区域科技重大项目(2011H41010083
