| Research Abstract |
We aimed to develop new photofunctionalized materials which posess selfcleaning, sterlization and deodorizing functions under weak UV light existing in a living environment. We previously developed such materials by coating various type of building materials such as ceramic tile, soda lime glass, paper, etc, by photoactive TiO_2 film with a thickness of less than 1mum. Based on those experiences, we studied following five topics in the present study.
1.Development of transparent TiO_2 film with higly photocatalytic activity.
2.Development of coating paint containing photoactive TiO_2 powder but stable even under UV light.
3.Development of cement material containing photoactive TiO_2 powder.
4.Characterization of surface properties of TiO_2 photocatalyst and evaluation of photocatalytic activities of the above materials.
5.Development of the methods to disperse photoactive TiO_2 powder in fluorein binder or inorganic binder.
