Method of photocatalytically making the surface of base material ultrahydrophilic, base material having ultrahydrophilic and photocatalytic surface, and process for producing said material

摘要

The invention relates to the use of a composite comprising a substrate and a photocatalytic layer coated thereon, said photocatalytic layer comprising a photocatalytic semiconductor material having a surface which has been rendered hydrophilic by photoexcitation with sunlight, for antifogging said surfaces. Said composite is, for example, a mirror, a lens or a transparent sheet member. IMAGE IMAGE IMAGE
