| 摘 要： | 采用电化学阳极氧化法,将纯钛浸入HF酸水溶液,在钛基体表面原位构建高度有序的二氧化钛纳米管阵列,探讨阳极氧化电压、电解液浓度和电解液温度等对二氧化钛纳米管阵列尺寸和形貌的影响。通过SEM、XRD对二氧化钛纳米管阵列的结构特征进行表征,结果表明,不同的阳极氧化电压、电解液浓度和温度都将影响TiO2纳米管阵列的尺寸和形貌,在阳极氧化电压为20V,HF电解液浓度为0.5%t条件下,可制备出结构规整有序的TiO2纳米管阵列。

| Abstract: | TiO_2 nanotube arrays were fabricated by anodic oxidation on a pure titanium in HF aqueous solution. It was studied that the influences of the parameters for the preparation of titania nanotube arrays on the micrograph of the material,such as anodizing potential,concentration and temperature of the electrolyte. The microstructures and morphologies of the TiO_2 nanotubes were investigated by scanning electron microscopy(SEM) and X-ray Diffraction(XRD).The results showed that TiO_2 nanotubes diameters and morphologies changed by altering of anodizing potential,concentration and temperature of the electrolyte. |
