| Research Abstract |
In the present study, mechanically stronger and higher functional photocatalytic film was developed with a help of surface micro-ploughing texture. In its fabrication, a pure titanium plate was scratched by a sharply pointed triangular diamond tip vibrated in the scratching depth direction at several mm in amplitude prior to the anodic-oxidation. As a result, it was found that the microtextured titanium dioxide film had a larger real surface area, which is advantageous to activate the photocatalytic reaction. And it was also clarified that the wettability, which is one of the photocatalytic functions, of the microtextured titanium dioxide film was superior to that of the mirror finished one.
