【摘要】 采用溶胶-凝胶工艺、分子模板法及提拉镀膜法,通过在TiO₂-SiO₂溶胶体系中掺杂十六烷基三甲基溴化铵（CTAB）,在普通钠钙硅酸盐玻璃衬底上沉积了TiO₂-SiO₂复合纳米孔薄膜。采用X射线衍射及扫描电镜（SEM）表征薄膜的微观结构。使用接触角测试仪测试镀膜玻璃的润湿性能,分析薄膜的组成和表面形貌与光学性能的关系。研究膜层中TiO₂与SiO₂比例对膜层折射率的影响,分析溶胶PH值及热处理温度和薄膜纳米孔结构的关系,对得到的结果进行讨论。更多还原

【Abstract】 Nano-porous TiO₂-SiO₂ composite thin films were prepared by sol-gel method using cetyltrimethylammonium-bromide（CTAB） as a cationic surfactant or molecular-template.UV-VIS spectrophotometer was used to characterize the optical properties of the films.The surface morphology was characterized with scan electron microscopy（SEM） and XRD.The water contact angle of the coating substrates was tested,and the relation of the surface composition and morphology to the optical properties and contact angle of the films was analyzed.更多还原
