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.
