The invention relates to a method for functionalising a surface of a solid substrate with at least one acrylic acid polymer layer, said method including the steps of: i) placing the surface in contact with a solution having of at least one acrylic acid homopolymer, a solvent and, optionally, metal salts; ii) removing the solvent from the solution in contact with the surface; and iii) binding the polymer to the surface by thermal treatment.

Surface functionalisation method

Nanofibres are provided that are insoluble and swellable in an essentially aqueous effluent, a method for the preparation of these nanofibres and the use of these nanofibres for the extraction from an effluent of metals, in particular metal salts originating from heavy metals, of rare earths, alkali metals, alkaline earth metals or actinides, in the stable or unstable isotopic forms thereof.

Swellable and insoluble nanofibers and use thereof in the treatment of essentially aqueous effluents

The invention related to a complexing system for extracting a radionuclide from a waste water solution including calix[n]arene groups on the surface of a porous conducting material.

Solid-liquid process for extraction of radionuclides from waste solutions

A method is provided for preparing an organic film on the surface of a solid support including the steps of (a) applying, to the surface, by transfer or by spraying, a solution containing at least one cleavable aryl salt; and (b) subjecting the solution to a UV or visible irradiation, such that irradiation radical entities are formed from the cleavable aryl salt and an organic film is grafted. Further provided is a kit of elements for the implementation of such a method.

Process for preparing an organic film at the surface of a solid support by transfer or by spraying

The present invention relates to a process for assembling at least one zone of a first surface with at least one zone of a second surface or with a molecule of interest, comprising a step that consists in placing the said zone of the said first surface in contact with the said zone of the said second surface or with the said molecule of interest, the said zone of the said first surface bearing at least one radical and/or ionic species. The present invention also relates to a solid support whose surface bears at least one zone with at least one radical and/or ionic species, with at least one adhesion primer, or with at least one adhesion primer precursor, and to its various uses.

Process for assembling two surfaces or one surface with a molecule of interest

An atomic force microscope probe comprising a piezo-electric resonator provided with two electrodes and coated with an insulating layer and a tip attached on the coated resonator and functionalized with at least one group or molecule of interest is disclosed. The disclosed technology also relates to preparation method and to different uses thereof.

Atomic force microscope probe, method for preparing same, and uses thereof

The invention relates to the deposition or attachment of materials to surfaces. It relates to a process for coating a surface with a first material and a second material, comprising the following steps: The object of the process of the invention is to allow the deposition of materials of any type onto surfaces of any type.

Surface-coating method

The present invention relates to a process for grafting and growing a conductive organic film on(to) an electrically conductive or semiconductive surface in which the grafting and growing of the film are performed simultaneously by electro-reduction of a diazonium salt that is a precursor of the said film on(to) the said surface cathodically polarized at a potential greater than or equal, in absolute value, to the electro-reduction potential of the diazonium salt relative to a reference electrode. The invention finds an application especially in the protection of surfaces, the manufacture of localized conductive coatings, of chemical sensors in the fields of chemistry and molecular biology, the manufacture of biomedical equipment, etc.

Method for grafting and growing a conductive organic film on a surface

The invention relates to a contact for an electrical contactor protected by a polymer film and to its production process. This contact (3 or 7) has a contact resistance of at the most 10 ohms and incorporates a base metal coated by a 5 to 500 nm, homogeneous, adhesive organic polymer film. The polymer film can be deposited by the electropolymerization of a monomer such as acrylonitrile, followed by a heat treatment or irradiation to improve its electrical conductivity, so that a contact resistance not exceeding 10 ohms is obtained.
