METHOD FOR CONTINUOUS PRODUCTION OF ALIGNED NANOSTRUCTURES ON A RUNNING SUBSTRATE AND RELATED DEVICE
Publication number: 20160289826Abstract: The invention relates to a method for continuously manufacturing aligned nanostructures on a running support, which comprises conveying the support through a heated space and synthesising, in this space, aligned nanostructures on the support by catalytic chemical vapour deposition. The heated space is divided into n consecutive zones in the conveying direction of the support (n being an integer ?2), and the synthesis of the nanostructures results from heating and injection operations, in each of these n zones, of a flux of an aerosol containing a catalytic precursor and a source precursor of the material of the nanostructures to be formed, carried by a carrier gas. The injection operations are made by modifying, in at least two of the n zones, at least one parameter chosen among the flow rate of the carrier gas flux, the chemical composition of the carrier gas, the mass concentration of the catalytic precursor in the catalytic precursor and source precursor mixture.Type: ApplicationFiled: November 14, 2014Publication date: October 6, 2016Applicant: COMMISSARIAT À L'ÉNERGIE ATOMIQUE ET AUX ÉNERGIES ALTERNATIVESInventors: Pascal BOULANGER, Martine MAYNE, Mathieu PINAULT, Emeline CHARON, Cecile REYNAUD -
Patent number: 9404106Abstract: A method for preventing, reducing and/or eliminating the fouling of a composite material is provided, the composite material comprising (1) a plurality of conductive or semiconductive nanotubes, which are aligned parallel to one another, and (2) a matrix arranged between the conductive or semiconductive nanotubes, the composite material in the form of an isoporous membrane with nanopores which correspond to the pores of the conductive or semiconductive nanotubes and optionally to the pores of the matrix arranged between the conductive or semiconductive nanotubes, the method comprising applying an electric field to the composite material, wherein the fouling is prevented, reduced and/or eliminated at the surface, at and in the pores of the composite material.Type: GrantFiled: October 8, 2012Date of Patent: August 2, 2016Assignee: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVESInventors: Pascal Boulanger, Alexandre Brouzes
