Title (EN) SELECTIVELY PERMEABLE GRAPHENE OXIDE MEMBRANE
(FR) MEMBRANE D'OXYDE DE GRAPHÈNE SÉLECTIVEMENT PERMÉABLE
Abstract:
(EN) Described herein are crosslinked graphene oxide and polycaroxylic acid based composite membranes that provide selective resistance for solutes while providing water permeability. Such composite membranes have a high water flux. The methods for making such membranes, and using the membranes for dehydrating or removing solutes from water are also described.
(FR) L'invention concerne un oxyde de graphène réticulé et des membranes composites à base d'acide polycarboxylique qui fournissent une résistance sélective aux solutés tout en fournissant une perméabilité à l'eau. De telles membranes composites ont un flux d'eau élevé. Les procédés de fabrication de telles membranes et l'utilisation des membranes pour la déshydratation ou l'élimination des solutés à partir de l'eau, sont également décrites.
