| 摘 要： | 将玻璃基底依次在低成本的SiO2溶胶和TiO2溶胶中浸渍后，在500 oC下煅烧制备了同时具备减反射与自清洁性能的SiO2/TiO2双层膜．该膜的光学性能与结构特征分别通过紫外-可见分光光度计和场发射扫描电镜进行了表征．同时，源于超亲水性和光催化作用的自清洁性能也凸显出来．实验结果表明制备SiO2/TiO2双层膜对光的透射率最高可达到95%，同时具备自清洁性能．

| Abstract: | SiO2/TiO2 double-layer films with antireflective and self-cleaning properties were prepared by dip-coating glass substrate into cost-effective SiO2 and TiO2 sol successively and subse-quently being calcined at 500 oC. The optical and structural properties of films have been in-vestigated by UV-visible spectrophotometer and field emission scanning electron microscope, respectively. At the same time, self-cleaning property generated from superhydrophilicity and photocatalysis was obtained. The results indicated that the as-prepared SiO2/TiO2 double-layer films show maximum transmittance of 95% and self-cleaning property. |
