  • LAYER-BY-LAYER ASSEMBLY OF GRAPHENE OXIDE MEMBRANES VIA ELECTROSTATIC INTERACTION AND ELUDICATION OF WATER AND SOLUTE TRANSPORT MECHANISMS
    Publication number: 20230114871
    Abstract: A method for synthesizing a water purification membrane is presented. The method includes stacking a plurality of graphene oxide (GO) nanosheets to create the water purification membrane, the stacking involving layer-by-layer assembly of the plurality of GO nanosheets and forming a plurality of nanochannels between the plurality of GO nanosheets for allowing the flow of a fluid and for rejecting the flow of contaminants. The method further includes cross-linking the plurality of GO nanosheets by 1,3,5-benzenetricarbonyl trichloride on a polydopamine coated polysulfone support.
    Type: Application
