The invention relates to a substrate comprising at least one photocatalytic compound active under the conditions of illuminating an interior of a building or transport vehicle, intended to neutralize the microorganisms with which it comes into contact, and also to its preparation processes and its uses as glazing or another substrate for disinfection, filtration, ventilation, etc.

Microbicidal substrate

This substrate is coated with a composite film based on a mesoporous mineral layer containing nanoparticles formed in situ inside the layer. The composite film has a periodic lattice structure over a major portion of the thickness in which the nanoparticles are present, in which structure the nanoparticles are arranged in a periodic manner on the scale of domains of at least 4 periods in the thickness of the film. This structure can be obtained from a mesoporous mineral layer of periodic structure on the scale of domains of at least 4 periods of pores, forming a matrix on the substrate, by: Applications to materials for electronics, nonlinear optics and magnetism.

Substrate coated with a composite film, method for making same and uses thereof

The substrate of the invention is coated with a mesoporous film. It is characterized in that chemical molecules, especially hydrophobic/oleophobic molecules, are bonded to the mesoporous film. The invention also relates to a process for manufacturing this substrate, in which: the substrate is brought into contact with a composition formed from organic assembling groups and from a precursor for the mesoporous material; the precursor precipitates around the assembling groups and polymerizes; and the assembling groups are removed. This process is distinguished by the fact that chemical molecules, such as hydrophobic/oleophobic molecules, are then brought into contact with the mesoporous film. The invention also relates to glazing, for buildings or transportation vehicles, which includes this substrate.
