process for photokatalytischen superhydrophilieren a surface of a substrate, a substrate with a superhydrophilen photokatalytischen surface and a procedure for its manufacture

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
