摘要： TiO2 possesses photocatalytic functions, even though they are relatively weak and required further enhancements for wider practical usages. On the other hand, improving materials surface functions by introducing surface textures is of great interest in various fields. This study aims to develop a high-functional photocatalytic surface by increasing the real surface area with the support of microcutting techniques. In this work, pure Ti plates, which was covered with numerous fine grooves fabricated by the microcutting and vibration-assisted microcutting techiniques, were anodized to obtain various regularly microtextured TiO2 film surfaces. Their wettabilties were examined to evaluate their photocatalitic potential. As a result, it is found that the wettability of the TiO2 film surfaces of regularly textured are superior to that of the mirror finished one under an ultraviolet rays irradiation environment.
