Substrates with self-cleaning coatings, e.g. for filter, windows, electronic components, have mesoporous structure with photocatalytic properties and comprises titanium oxide at least partially crystallized

摘要

A substrate has a coating on at least a part of its surface, having a mesoporous structure with photocatalytic properties and comprises titanium oxide at least partially crystallized. The optionally transparent substrate may be glass- or polymer-based or a ceramic or vitroceramic substrate or a building material, such as a facade coating, flagstones or pavings made from concrete, construction concrete, tiles, cement materials, terracotta, slate, stone, metal surfaces or glassy fibrous substrates, such as mineral insulation wool or glass reinforcement threads.
