Abstract

La presente divulgacion se refiere a membranas de desalinizacion basadas en nanotubos de carbono y a metodos de fabricacion de las mismas. Las membranas de desalinizacion de nanotubos de carbono pueden fabricarse: proporcionando una matriz polimerica; proporcionando nanotubos de carbono que entran directamente en contacto con la matriz polimerica; agitando los nanotubos de carbono en la matriz polimerica para hacer una solucion de composite de nanotubos de carbono; y recubriendo un sustrato con la solucion de composite de nanotubos de carbono para formar una membrana de desalinizacion de nanotubos de carbono. Las membranas de desalinizacion de nanotubos de carbono pueden proporcionar un caudal superior y altos niveles de rechazo de sales.
