Abstract:
1. A process whereby a material obtained comprising a substrate of which at least a part of the surface of at least one of the faces of the substrate is based on organic compounds, said process being implemented at atmospheric pressure and without heating the totality of said substrate, said process comprising moreover the following stages: In immediate proximity to said substrate creating a region containing active species of a non-thermal plasma, Into said region injecting at least one precursor of a chemical element so as to deposit onto at least one face of said substrate, at least one part of the surface being based on organic compounds, a first thin layer able to protect said substrate against oxidation reactions due to radicals, said at least one precursor being selected to provide a first thin layer comprising silicon and oxygen, and subsequently depositing a second thin layer with photocatalytic properties onto the first thin layer.
