Title
(EN) GRAPHENE MEMBRANES AND METHODS FOR MAKING GRAPHENE MEMBRANES
(FR) MEMBRANES EN GRAPHÈNE ET PROCÉDÉS DE FABRICATION DE MEMBRANES EN GRAPHÈNE
Abstract
(EN)
A method for making a graphene membrane includes applying a suspension of graphene platelets in a fluid onto a porous substrate, and applying a pressure differential to force the fluid through the substrate to yield a filtered fluid while retaining the graphene platelets on the substrate. The graphene platelets and the substrate form the graphene membrane.
(FR)
Un procédé de fabrication d'une membrane en graphène comprend l'application d'une suspension de plaquettes de graphène dans un fluide sur un substrat poreux, et l'application d'un différentiel de pression pour forcer le fluide à travers le substrat pour produire un fluide filtré tout en retenant les plaquettes de graphène sur le substrat. Les plaquettes de graphène et le substrat forment la membrane de graphène.
