Title (EN) PERMEABLE GRAPHENE AND PERMEABLE GRAPHENE MEMBRANES
(FR) GRAPHÈNE PERMÉABLE ET MEMBRANES EN GRAPHÈNE PERMÉABLE
Abstract:
(EN) Continuous permeable graphene films having 2 or more layers of graphene and wherein nanochannels or nanopores extend through said film. Each nanochannel is comprised of a fluidly connected series of gaps between edge mismatches of adjacent graphene grains within said 2 or more layer adjacent sheets, said nanochannels providing a fluid passage from one face of the permeable graphene film to the other. Also, membranes including a permeable support membrane overlaid by a continuous permeable graphene film and processes for the preparation of said membranes. Also the use of said membranes in water purification and desalination, for example.
(FR) L'invention concerne des films de graphène perméables continus ayant 2 couches ou plus de graphène et dans lesquels des nanocanaux ou des nanopores s'étendent à travers ledit film. Chaque nanocanal est constitué d'une série d'espaces connectés fluidiquement entre des mésappariements de bord de grains de graphène adjacents à l'intérieur desdites 2 ou plusieurs feuilles adjacentes de couche, lesdits nanocanaux fournissant un passage de fluide d'une face du film de graphène perméable à l'autre. L'invention concerne également des membranes comprenant une membrane de support perméable recouverte d'un film de graphène perméable continu et des procédés de préparation desdites membranes. L'invention concerne également l'utilisation desdites membranes dans la purification et le dessalement de l'eau, par exemple.
