英文摘要	针对粗糙度致超亲水和光致超亲水所存在的不足之处,提出一种粗糙度与光协同效应致超亲水的方法.以钛酸正丁酯(TbOT)和正硅酸四乙酯(TEOS)为原料,采用溶胶-凝胶法制备TIO2、不同PH值的SIO2和SIO2-TIO2复配溶胶,利用浸渍提拉法在玻璃基片上镀制SIO2纳米薄膜、TIO2纳米薄膜和SI-TI复合纳米薄膜.通过动态光散射分析仪(dlS)对SIO2和TIO2溶胶的粒径进行测定,分别用接触角测定仪(CAM)和原子力显微镜(AfM)对纳米薄膜的亲水性能和表面粗糙度进行表征.实验结果表明:碱性SIO2纳米薄膜具有粗糙度致超亲水的性能,TIO2纳米薄膜具有光致超亲水的性能,而当SI摩尔分数为20%时,SI-TI复合纳米薄膜具有粗糙度与光协同效应致超亲水的性能.; Aiming at the deficiencies in the methods of light-induced superhydrophilicity and roughness-driven superhydrophilicity at present,a method of light-induced superhydrophilicity and roughness-driven superhydrophilicity synergistic effect was applied to prepare superhydrophilic films.The SiO2,TiO2and Si-Ti composite nanometer thin films were prepared on common glass substrates by sol-gel processing and dip-drawing method.The diameters of the SiO2and TiO2nanoparticles in sol were determined by dynamic light scattering analyzer(DLS).The superhydrophilic property and surface roughness of these films were characterized by contact angle measurement(CAM)and atomic force microscope(AFM),respectively.The results indicate that the SiO2nanometer thin film has roughness-driven superhydrophilicity,and the TiO2nanometer thin film has light-induced superhydrophilicity.The Si-Ti composite nanometer thin film with 20%(by mol.)silicon content has a synergistic effect of light-induced and roughness-driven superhydrophilicity,and present excellent superhydrophilic property in all weather.; 校企合作项目(0042-K81280)
