Title
(EN) COMPOSITE MEMBRANES COMPRISING NANOPARTICLES FOR LIQUID FILTRATION
(FR) MEMBRANES COMPOSITES COMPRENANT DES NANOPARTICULES POUR FILTRATION DE LIQUIDE
Abstract
(EN) A filter membrane includes carbon nanotubes and carbon nitride nanoparticles. Inter-particle atomic interactions between the carbon nanotubes and the carbon nitride nanoparticles bind the carbon nanotubes and the carbon nitride nanoparticles together. A filter cartridge includes such a filter membrane disposed within an outer housing between a fluid inlet and a fluid outlet such that fluid passing through the outer housing between the fluid inlet and the fluid outlet passes through the filter membrane. Such filter membranes may be formed by dispersing carbon nanotubes and carbon nitride nanoparticles in a liquid to form a suspension, and passing the suspension through a filter to deposit the nanotubes and nanoparticles on the filter. Liquid may be filtered by causing the liquid to pass through such a filter membrane.
(FR) La présente invention concerne une membrane de filtration qui comprend des nanotubes de carbone et des nanoparticules de nitrure de carbone. Selon l'invention, des interactions atomiques inter-particulaires entre les nanotubes de carbone et les nanoparticules de nitrure de carbone, lient les nanotubes de carbone et les nanoparticules de nitrure de carbone ensemble. Une cartouche filtrante comprend une telle membrane de filtration disposée à l'intérieur d'un boîtier externe entre une entrée et une sortie de fluide, de telle sorte que le fluide passant à travers le boîtier externe entre l'entrée et la sortie de fluide passe à travers la membrane de filtration. Les membranes de filtration de l'invention peuvent être formées par dispersion de nanotubes de carbone et de nanoparticules de nitrure de carbone dans un liquide pour former une suspension, et par passage de la suspension à travers un filtre pour déposer les nanotubes et les nanoparticules sur le filtre. Un liquide peut être filtré en le faisant passer à travers une membrane de filtration de l'invention.
