在常温下,以钛酸丁酯[(C4H9O)4Ti]和聚四苯乙烯磺酸钠(PSS)作为前驱物在普通载玻片上用离子自组装法制备了TiO2纳米粒子/PSS复合薄膜,复合薄膜的透过率随镀膜次数或薄膜厚度的增加而呈现周期性变化.透射电镜(TEM)测试结果表明,TiO2呈板钛矿晶体结构,薄膜连续而均匀,TiO2的平均粒径是3.6nm.光电子能谱仪(XPS)测试结果显示,薄膜中含有Ti、O、C元素,载玻片表面完全被TiO2纳米复合薄膜所覆盖.

TiO2/polymer composite thin films were prepared on the ordinary glass substrates at room temperature byionicallyselfassembly method with tetrabutylorthotitanate [ ( C4 H9 O) 4 Ti] and Poly (Sodium-4-styrensulfonate) Salt (PSS) as precursor.Transmittance of TiO2 thin films presented a periodic change with the increasing of coating cycle times or thin films thickness.Transmission electron microscopy(TEM) data showed that TiO2 presented brookite phase structure. TiO2 thin films were uniform and continuous in thickness. The average grain size of TiO2 in thin films was 3.6nm. X-ray photoelectron spectroscopy(XPS) data showed that TiO2 thin films contained Ti,O,C elements. Surface of ordinary glass was completely covered with TiO2thin films.
