Growth of TiO2 Nanotube Arrays (TNAs) by Current Control Anodizing

摘要

The paper studies the thin film of TiO2 nanotube arrays about diameter of 40 μm, which grown by electrochemically second anodization using titanium foil. The structure and compositions of nanotube arrays were characterized by scanning electron microscopy (SEM). Use the same electrolytes solution can grown three samples of TiO2 nanotube arrays under different times. That will be accordingly economize on electrolytes, and save on the time.
