Outline of Final Research Achievements

UV light treatment is thought to counteract biological aging of titanium implant. UV light treatment of aged titanium surfaces decomposes hydrocarbons by inducing photocatalytic activity and restores superhydrophilicity. I focused on the effect of hydrocarbon decontaminantion on the titanium surfaces. In this study, I examined the hypothesis that UV light pretreatment of TiO2 accelerates a photocatalytic reaction and enchances the bleaching effect of the TiO2-H2O mixture. I investigated the photocatalytic activity by measuring the color change before and after the bleaching. The results suggested that the appropriate pretreatment condition can maximize the bleaching effect of the TiO2-H2O mixture.
