| 摘 要： | 以钛酸的纳米单片层为前驱体,采用电泳沉积法在Pt极板上制备择优取向钛酸薄膜,并通过热处理使其转换成TiO2薄膜。考察了悬浮介质和沉积电压对钛酸薄膜形貌及结构的影响,通过XRD、SEM对薄膜进行了表征。结果表明:在乙醇:水为1:1的悬浮介质中沉积制得的钛酸薄膜均匀、平整、致密,具有很强的b轴取向;薄膜的厚度随电压的升高而增厚;经500℃热处理后,钛酸薄膜转变成具有(101)择优取向的锐钛矿相结构的TiO2薄膜,颗粒尺寸分布均匀,平均粒度约40nm。

| Abstract: | Highly oriented titania thin films on Pt substrate were fabricated by electrophoretic deposition using the titania nanosheets as precursor.The titania thin films can be transformed to titanium oxide thin films when they are heated.The influence of suspension and deposition voltage on the formation of the film was investigated in this paper.The structure and morphology of thin films were characterized by X-ray diffraction and field-emission scanning electron microscopy.It is found that a film with smooth sur... |
