| 摘 要： | 以钛酸丁酯作为前驱物，采用溶胶-凝胶法及浸渍-提拉法在载玻片上制备SrO-TiO2薄膜。通过X射线衍射和红外光谱等测试技术表征了SrO-TiO2粉末的结构，用紫外可见分光光度计测定薄膜的透光率，用接触角测试仪测定水与薄膜的接触角。结果表明，掺杂适量Sr2+后，SrO-TiO2粉末中TiO2晶粒的尺寸变小，SrO-TiO2薄膜表面吸附的羟基含量增多且稳定，可提高TiO2薄膜的超亲水性。经紫外光照１ｈ或自然光照５ｈ后，掺杂Sr2+（摩尔分数））为1.0％的SrO-TiO2薄膜与水的接触角接近于0°，表现出良好的亲水性。

| Abstract: | SrO-TiO2 films on glass slides were prepared via sol-gel process and dip-coating technique using tetrabutyl titanate as a precursor.The structure of SrO-TiO2 powder was characterized by XRD and IR.The transmission rates of the films were measured by UV-Vis spectroscopy.The water contact angles of the films were also measured.The results obtained are as follows:the grain size of TiO2 in the SrO-TiO2 powder became smaller when a proper amount of Sr2+ was introduced.The hydroxyl content on the surface of the t... |
