  • Patent number: 8263488
    Abstract: 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: placing the first material on the said surface, inserting into the first material placed on the said surface precursor molecules of the second material, converting the said precursor molecules of the second material inserted into the first material into the said second material such that this second material becomes formed on the said surface to be coated and within the said first material placed on the said surface. The object of the process of the invention is to allow the deposition of materials of any type onto surfaces of any type.

  • Patent number: 7736484
    Abstract: 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.

  • Patent number: 5350323
    Abstract: 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.
