Fabrication of Anodic TiO2 Nanotube Arrays in Ethylene Glycol-Based Electrolyte
Abstract: Single-layer and two-layer TiO2 nanotube arrays were fabricated by anodization of pure Ti in ethylene glycol-based electrolyte containing 0.3 wt.% NH4F and 6 vol.% distilled water in potentiostatic and in-situ voltage up mode respectively. The top-view or cross-sectional morphologies were observed by scanning electron microscope. The effects of applied voltage and anodization time on tube diameter and tube length were studied, as well as their quantitative relationships were preliminarily summarized. The results show that the tube diameter and the length of TiO2 nanotube arrays increase with the applied voltage, and there is a linear dependence between tube diameter and potential in a certain range. The growth rates of the tube length are different at different voltage. The tube length linearly increases with the anodization time, while the tube diameter is little affected by the anodization time.
