The invention relates to a substrate () provided with a thin-film multilayer comprising an alternation of n functional layers () having reflection properties in the infrared and/or in solar radiation, and (n+1) coatings (), where n&#x2267;1, said coatings being composed of a layer or a plurality of layers (), characterized in that, in order to preserve the optical and/or mechanical quality of the multilayer in the case in which the substrate () provided with said multilayer is subjected to a heat treatment of the toughening, bending or annealing type, at least one of the functional layers () includes a blocker coating () consisting of:

Substrate with a stack having thermal properties

The invention relates to a structure, comprising a substrate supporting a layer with a photocatalytic and anti-soiling property, said layer being based on titanium dioxide (TiO), on at least part of the surface thereof. Said structure is characterized in that the photocatalytic layer is coated with a non-porous thin layer, containing silicon and oxygen and having a coating capacity, providing a chemical and mechanical protection to the underlying photocatalytic layer, while maintaining the TiOphotocatalytic activity.

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

The invention relates to a structure, comprising a substrate supporting a layer with a photocatalytic and anti-soiling property on at least part of the surface thereof, said layer being based on titanium dioxide (TiO) which is at least partially crystallized in the anatase form thereof. Said structure is characterised in comprising a sublayer (SC) directly under at least one TiOlayer, said sublayer having a crystallographic structure which provides assistance to crystallization by heteroepitaxial growth in the anatase form of the TiO-based upper layer, the photocatalytic property being obtained without any heating step.

Substrate, in particular glass substrate, supporting at least one stack of a photocatalytic layer and a sublayer for the heteroepitaxial growth of said layer
