摘要:
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.
