The purpose of the invention is a process for obtaining a material comprising a substrate at least part of whose surface and at least one of whose faces is based on organic compounds, the said process being implemented at atmospheric pressure comprises moreover the following stages: In the immediate vicinity of the said substrate a zone containing active species of a non-thermal plasma is created; into the said zone is injected at least one precursor of a chemical element so as to deposit upon at least one face of the said substrate (at least part of whose surface comprises an organic compound base), a first thin layer capable of protecting the said substrate against oxidation reactions, specifically those due to radicals. A further purpose of the invention is the material obtainable according to this process.

Process for depositing a thin layer and product obtained thereby

A method for manufacturing a structure having a textured surface, including a substrate made of mineral glass having a given texture, for an organic-light-emitting-diode device, the method including supplying a rough substrate, having a roughness defined by a roughness parameter Ra ranging from 1 to 5 &#x3bc;m over an analysis length of 15 mm and with a Gaussian filter having a cut-off frequency of 0.8 mm; and depositing a liquid-phase silica smoothing film on the substrate, the film being configured to smooth the roughness sufficiently and to form the textured surface of the structure.

Method for manufacturing a structure with a textured surface for an organic light-emitting diode device, and structure with a textured surface

A substrate bearing, on one main face, a composite electrode, which includes an electroconductive network formed from strands made of an electroconductive material based on a metal and/or a metal oxide, and having a light transmission of at least 60% at 550 nm, the space between the strands of the network being filled by a material referred to as an insulating fill material. The composite electrode also includes an electroconductive coating covering the electroconductive network, and in electrical connection with the strands and in contact therewith, having a thickness greater than or equal to 40 nm, of resistivity &#x3c1;1 less than 10&#x3a9;&#xb7;cm and greater than the resistivity of the network, the coating forming a smoothed outer surface of the electrode. The composite electrode additionally has a sheet resistance less than or equal to 10&#x3a9;/&#x25a1;.

The invention relates to a transparent substrate based on glass or one or more polymers, or a ceramic or glass substrate, or a substrate made of architectural material of the type comprising a wall render, a concrete slab or block, architectural concrete, roof tile, material of cementitious composition, terracotta, slate, stone, metal surface or a fibrous substrate, based on glass of the mineral insulation wool type, or glass reinforcement yarns. This substrate is distinguished in that it is provided, on at least part of its surface, with a coating whose mesoporous structure exhibits photocatalytic properties and comprises at least partially crystallized titanium oxide. Process for manufacturing this substrate, its application in glazing, as architectural material or as mineral insulation wool is also described.

Substrate with a self-cleaning coating

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: Applications to materials for electronics, nonlinear optics and magnetism.
