Patent number: 6627319Abstract: 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.Type: GrantFiled: June 21, 2001Date of Patent: September 30, 2003Assignee: Saint-Gobain Glass FranceInventors: Catherine Jacquiod, Jean-Marc Berquier, Laurent Teyssedre, Marie-José Azzopardi
