Self-Assembled TiO2 Nanotube Arrays with U-Shaped Profile by Controlling Anodization Temperature

الملخص EN

TiO2 nanotube arrays with uniform diameter from top to bottom were fabricated.

The synthesizing approach is based on the investigation of the influence of electrolyte temperature on the tube diameter.

We found that the inner diameter of the tubes increased with the electrolyte temperature.

Accordingly, we improved the tube profile from the general V shape to U shape by raising the electrolyte temperature gradually.

This is a simple and fast approach to fabricate uniform TiO2 nanotubes in diameter.

The improved TiO2 nanotube arrays may show better properties and have broad potential applications.
