中文摘要：

以NH4F／乙二醇为电解液对Ti箔进行阳极氧化，通过对溶液中水的含量、氧化电压、时间等参数的控制，制备了高度有序TiO2纳米管．分别利用XRD和SEM对TiO2纳米管阵列的物相组成和形貌结构进行了表征，结合氧化过程电流密度变化探讨了TiO2纳米管的生长机理．研究结果表明：TiO2纳米管阵列的形成须经历致密氧化层的形成、多孔层的形成以及纳米管的形成与稳定生长3个阶段的演化．

英文摘要：

Ti foil was anodized in ethylene glycol and NH4F etectrolyte, and highly ordered arrays of TiO2 nanotube（NT） were fabricated by varying anodization parameters, including the water content in etectrolyte, anodizing voltage, pH value and bath temperature. The phase of the nanotube was analysed by X-ray diffraction,its shape was observed by SEM and the mechanism of NT array formation was discussed with reference to the curve of current density to time. The formation of TiO2 NT undergoes 3 steps.oxide layer formation, pit formation on the oxide layer, and the shaping and stable growth of the NT.
