Title:
SELECTIVELY PERMEABLE GRAPHENE OXIDE MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2018/160871
Kind Code:
A3
Abstract:
Described herein is a graphene and polyvinyl alcohol based multilayer composite membrane that provides selective resistance for solutes to pass the membrane while providing water permeability. A selectively permeable membrane comprising a crossiinked graphene with a polyvinyl alcohol and silica-nanoparticle layer that can provide enhanced salt separation from water, methods for making such membranes, and methods of using the membranes for dehydrating or removing solutes from water are also described.
