Abstract: The invention relates to a method of producing a substrate which is coated with a mesoporous layer and to the use thereof in ophthalmic optics. The inventive method comprises the following steps comprising: preparing a precursor sol containing (i) a precursor agent that is selected from compounds having formula M(X)4 (I), in which X is a hydrolysable group and M represents silicon or a tetravalent metal and mixtures thereof, (ii) at least one organic solvent, (iii) at least one pore-forming agent and (iv) water; depositing a film of the precursor sol on a main surface of the substrate; optionally consolidating the mesoporous structure of the deposited film; eliminating the pore-forming agent; and recovering the substrate coated with the mesoporous layer. The method is characterized in that: (i) the pore-forming agent is eliminated at a temperature of less than or equal to 150° C.; and (ii) the method comprises a step involving the introduction of at least one reactive agent bearing at least one hydrophobic group, before the deposition step and/or after said step.

Abstract: The present invention relates to a method for making a substrate coated with a mesoporous photochromic film, comprising: a) preparing a precursor sol of a mesoporous film comprising an inorganic precursor agent, at least one organic solvent, water, at least one pore-forming agent and one hydrophobic precursor agent bearing at least one hydrophobic group; b) depositing a film of the precursor sol onto a main surface of a substrate; c) removing the pore-forming agent from the film resulting from the previous step at a temperature @150° C.; d) impregnating the mesoporous film resulting from step c) with a solution comprising at least one photochromic agent. In an alternative embodiment, the photochromic agent is directly introduced into the precursor sol. In an alternative embodiment of the previous alternative embodiment, the precursor sol does not comprise any hydrophobic precursor agent but the photochromic film is made hydrophobic by a treatment subsequent to its preparation.
