摘 要: 用溶膠-凝膠法和高溫煅燒在玻璃基體上制備納米TiO2薄膜，測(cè)試在各種工藝條件下制備的薄膜的親水性、紫外線激發(fā)活性等性能，利用X射線衍射法和掃描電鏡法表征其顯微結(jié)構(gòu)，并重點(diǎn)進(jìn)行了涂層層數(shù)和保溫時(shí)間對(duì)顯微結(jié)構(gòu)性能影響的研究。結(jié)果表明，涂層層數(shù)增加和保溫時(shí)間延長(zhǎng)不影響涂層中銳鈦礦晶型的穩(wěn)定性，對(duì)納米TiO2的顆粒長(zhǎng)大也無(wú)明顯影響。

Abstract:The nanometer TiO2 film was prepared on the glass body by means of sol-gel method and high temperature firing process. The super-hydrophilicity and ultraviolet ray activation of the film produced in different technical conditions were tested. The characteristics of the microstructure for film were determined by means of XRD and SEM method. The focal point of study is the effect of coating layer number and soaking time on the microstructure of nanometer TiO2 film. The results show that crystallography stability of anatase in nanometer TiO2 film is not affected by the increasing of layers and prolonging of soaking time, and no significance grain growth can be observed under those conditions.
Key words: nanometer; TiO2；film；coating layer number；soaking time
