摘要
以钛酸正丁脂 [Ti( OC4 H9) 4]为原料 ,采用溶胶 -凝胶法和浸渍提拉法 ,在自制的陶瓷釉体表面制得粒径大小为 4 0~ 10 0 nm的 Ti O2 晶粒 ,它紧密结合形成 ,透明均一无“彩虹效应”的 Ti O2 光催化薄膜型自洁功能陶瓷 ,具有超级亲水性和去污功能 ;以甲基橙为有机污染模拟物 ,对钛酸正丁脂的用量、灼烧温度和时间 ,涂膜层数等制备条件进行研究 ,得出了较优化的制备条件 .
A kind of ceramic with a transparent and flat thin film composed by 40~100 nm size TiO 2 particles was prepared by sol-gel and dipping methods using Ti(OC 4H 9) 4 as precursor. The film was assembled over the ceramic glaze layer, of which the composition was self developed. The ceramic possesses superhydrophilic, self-cleaning and decontaminating functions. Using methyl orange as organic contaminant, optimum conditions were drawn out for the preparation of the ceramic by investigating the affections of the quantity of Ti(OC 4H 9) 4 , calcining temperature and time and the layers of the films.
