Surface Wettability Change by Irradiation

10.2.1 Sample and Irradiation Facility

To investigate surface wettability change by irradiation, samples are irradiated by using an ultraviolet lamp, a 60Co y-ray source, and a proton accelerator. In this study, a TiO2 sample, which is a typical photocatalyst [10], is used to compare the irradiation effects of ultraviolet, y-ray, and proton beam. TiO2 is prepared through anodizing a 0.1-mm-thick titanium plate [11]. Details of the experimental proce­dure with TiO2 samples and irradiation facilities are described as follows.
