TiO2致密度膜电阻水热法取向生长TiO2 Density Film Resistance Hydrothermal Method Oriented Growth


TiO2薄膜的致密度和膜电阻对TiO2材料的功能应用有非常重要的影响。本文采用传统水热合成方法,通过调节前驱液中乙醇和水的比例,制备出了不同致密度和膜电阻的取向生长TiO2纳米柱阵列薄膜(TiO2nano-rods arrays film, TNRAF)。结果表明,乙醇的添加对TNRAF的形貌及取向生长有很大的影响。乙醇含量增加,TNRAF的(002)取向生长明显增强,粒径变小,表面形貌光滑,表面裂纹增加,初始电阻逐渐增加。

Fabrication of titania (TiO2) with specific film density and resistance is of great importance to functional application of TiO2-based materials. In this work, by using hydrothermal method, we prepared TiO2 Nano-Rods Arrays Film (TNRAF) with different crystal orientation and morphologies via adjusting the ratio of absolute ethyl alcohol to deionized water in hydrothermal precursor. The results indicated that (002) oriented growth of the thin films was obviously enhanced by increasing the content of absolute ethyl alcohol. Diameter of the nanorods in TNRAF decreased; surface of TNRAF got smoother; more cracks appeared on the surface of the thin films; and the initial resistance of TNRAF grew bigger.
