摘要
采用两步施加电压的阳极氧化方法制备了具有不同形貌的氧化钛薄膜,使用扫描电子显微镜对在不同初始电压、不同放电电压下制备的氧化钛薄膜的形貌进行了分析。结果表明,在相同的放电电压下,通过改变初始电压可以制备出具有不同平均孔径和平均孔密度的阳极氧化钛薄膜;在一定的初始电压下,放电电压有一定的极限值,超过这个极限值电极将被烧毁;在初始电压60V,放电电压140V条件下制备的阳极氧化钛薄膜的纳米孔最规整、分布最均匀、孔径最均一。
TiO2 thin films with different morphologies were prepared by a two-step anodic oxidation method.The morphologies of TiO2 films prepared under different initial voltages and different discharge voltages were analyzed by scanning electron microscopy.The results reveal that TiO2 films with different average pore diameters and different average pore densities can be prepared under the same discharge voltage but different initial voltages.When the initial voltage is at a certain value the discharge voltage has a limit,higher than which the electrode will be burned out.The anodizing TiO2 film prepared under conditions of initial voltage 60V and discharge voltage 140V shows the best morphology which possesses the most structured nano-pores with the most symmetrical pore distribution and pore diameter.
