摘要/Abstract

摘要： 采用溶胶-凝胶法, 在FTO(SnO₂:F)低辐射镀膜玻璃衬底上制备了柱状晶体结构的TiO₂薄膜, 获得双层结构FTO/TiO₂镀膜玻璃样品. 研究了TiO₂薄膜厚度对FTO/TiO₂镀膜玻璃样品的光催化活性、低辐射性能以及透光性能的影响. 结果表明, FTO/TiO₂镀膜玻璃样品光催化活性随着TiO₂薄膜厚度的增加先升高后下降, 在TiO₂薄膜厚度为300 nm时光催化活性最佳; 低辐射性能随着TiO₂薄膜厚度的增加而下降, 但TiO₂薄膜厚度为300 nm时仍然具备一定的低辐射性能; 透光性能与TiO₂薄膜膜厚的关系不大, 可见光透射比保持在72%左右; 表面平均粗糙度约为1 nm, 表面光滑, 不易沾染油污灰尘. 该镀膜玻璃在保证低辐射建筑节能和透光的前提下, 兼具光催化自清洁功能, 具有很好的应用前景.

Abstract: Columnar crystal structured TiO₂ thin films were prepared on the FTO (SnO₂: F) low-emissivity coated glass substrates, obtaining double-layer structure FTO/TiO₂ coated glass samples. The effect of TiO₂ film thickness on the photocatalytic activity, the low-emissivity performance and light transmission properties of the FTO/TiO₂ coated glass samples was investigated. The results showed that the photocatalytic activity of the samples increased firstly and then decrease with the increase of the film thickness. The best catalytic activity was observed for the sample coated with 300 nm TiO₂ film. The low-emissivity properties of the samples declined as the TiO₂ film thickness increased. The sample still have some low-emissivity performance when the TiO₂ film thickness is 300 nm, while the light transmittance of the samples have little relations with the TiO₂ films thickness. The visible light transmittances of the samples remain at about 72% with a smooth surface. The average surface roughness of the sample is about 1 nm. The FTO/TiO₂ coated glass has photocatalytic self-cleaning properties with excellent low emissive performance and light transmittance property, thus guaranteeing good application prospects.
