Title
(EN) GRAPHENE NANO COMPOSITE POLYMERIC MEMBRANE AND METHOD THEREOF
(FR) MEMBRANE POLYMÈRE DE NANOCOMPOSITES DE GRAPHÈNE ET PROCÉDÉ ASSOCIÉ
Abstract
(EN) Graphene nano-composite polymeric membrane wherein graphene oxide is synthesized by modified hummers method, graphene oxide is then doped with sulphur and substituted with amino group followed by silver crosslinking. The present invention can be used in high performance masks and air purifiers that has the application in graphene based advanced materials in air filtration membranes.
(FR) L’invention concerne une membrane polymère de nanocomposites de graphène, l’oxyde de graphène étant synthétisé par une méthode de Hummer modifiée, l’oxyde de graphène étant ensuite dopé avec du soufre et substitué par un groupe amino, l’opération étant suivie d’une réticulation de l’argent. La présente invention peut être utilisée dans des masques et des purificateurs d’air hautes performances et présente une application dans des matériaux évolués à base de graphène dans des membranes de filtration d’air.
