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.

我们的目标是开发新型光功能化材料，在生活环境中存在的弱紫外线下具有自清洁、杀菌和除臭功能。我们之前通过在瓷砖、钠钙玻璃、纸张等各类建筑材料上涂覆厚度小于1μm的光敏TiO_2薄膜来开发此类材料。基于这些经验，我们在本研究中研究了以下五个主题：1.开发具有高光催化活性的透明TiO_2薄膜。2.开发含有光活性TiO_2粉末但在紫外光下也稳定的涂料。3.水泥材料的开发含有光活性TiO_2粉末。4.TiO_2光催化剂的表面性能表征以及上述材料的光催化活性评价。5.分散光活性方法的开发TiO_2粉末在氟粘结剂或无机粘结剂中。
