摘要
采用电化学阳极氧化法制备了高度有序TiO2纳米管阵列,并提出纳米管"兼并"的概念。结合FE-SEM分析并验证了Macak等人提出的pH值梯度理论,并在此基础上用双电层理论解释了"兼并"的形成机理,同时解释了初期纳米管管径进一步增大的原因。
In this article, highly ordered TiO2 nanotube arrays were prepared by electrochemical anodization. The concept of ' mergers' was proposed, pH gradient theory put forward by Macak was verified with SEM images and the formation mechanism of ' mergers' of titania nanotubes was explained by the effect of electric double layer. The reasons of the further augment of original nanotubes diameters were also analyzed.
