Substrate, in particular glass substrate, supporting a photocatalytic layer coated with a protective thin layer

摘要

A structure comprises a substrate carrying, on at least a part of its surface, a titanium oxide (TiO2) based layer with photocatalytic, anti-stain properties. This layer is coated with a non-porous covering thin film with a silicon and oxygen content, able to assure a mechanical and chemical protection of the underlying photocatalytic layer by retaining the photocatalytic activity of the TiO2. - Independent claims are also included for: - (a) the fabrication of this structure; - (b) a single or multiple glazing for a motor vehicle or building incorporating this structure.
