  • Patent number: 7348054
    Abstract: 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: depositing at least one precursor in the pores of the matrix layer; and growing particles derived from the precursor with the spatial distribution and the dimensions being controlled by the structure of the pores of the matrix. Applications to materials for electronics, nonlinear optics and magnetism.

  • Patent number: 6627319
    Abstract: 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.

  • Patent number: 5389427
    Abstract: The present invention concerns a non-wettable glass sheet comprising a hydrophobic, oleophobic, UV resistant layer and a process for manufacturing the same. The process in accordance with the present invention includes cleaning the glass sheet, contacting the glass sheet with a solution containing a fluorinated organosilane in a non-polar solvent system at a temperature ranging between -10.degree. C. and 25.degree. C. for at least 5 minutes, and rinsing.
