Light-scattering materials which have self-cleaning sufraces

摘要

A light-scattering material includes a coating with self-cleaning properties on a transparent substrate. Particles randomly distributed in and on the coating roughen the coating and provide a surface structure that scatters light. The light-scattering material is useful in providing indirect illumination, particularly using daylight. The coating can have antimicrobial properties. The light-scattering material can require significantly less maintenance than conventional light-scattering materials.
