Abstract:
The invention relates to a method of fixing macro-objects to an electricity conducting- or semi-conducting surface by means of electrografting. The invention also relates to the electricity conducting- or semi-conducting-surfaces obtained using the aforementioned method and to the applications of same.
Abstract:
The invention relates to a method for forming a polymer film on a surface that conducts or semiconducts electricity by means of electrografting. Said method uses an electrolytic solution containing a selected quantity of Brönsted acid. The invention also relates to the electrically conductive or semiconductive surfaces obtained by means of said method.
Abstract:
The invention relates to a bioactive implant comprising a substrate coated with a polymer layer with reactive functions, and a bioactive substance fixed on the implant by means of said reactive functions to enable progressive release on the implant site. Such implants are useful in the field of cardiology for example to prevent restenosis resulting from the fitting of stents in the coronary arteries.
Abstract:
The present invention relates to a method for cladding a simple or complex surface, electrically conducting or semiconducting, by means of an organic film from at least one precursor of said organic film, characterized in that the cladding of the surface by the organic film is carried out by electro-initiated grafting of said, at least one, precursor of said surface by applying at least one potential sweep on this surface carried out in such a way that at any point of said surface the maximum potential of each potential sweep, in absolute value and relative to a reference electrode, is greater than or equal to the value of the potential (vbloc) from which the curves of a graph expressing the quantity of electro-grafted precursor on a surface identical to said surface in function of the number of potential sweeps are all superposed and independent of this vbloc potential.

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.
Abstract:
The use of at least one diazonium salt bearing an initiator function, for forming an undercoat obtained by grafting a graft derived from the diazonium salt and bearing an initiator function at the surface of a conductive or semiconductive material on the undercoat, and for forming on the undercoat a polymeric layer obtained by polymerization, in particular free radical polymerization, in situ of at least one monomer, initiated from the initiator function.
Abstract:
