Abstract: Described herein is a crosslinked graphene and biopolymer (e.g. lignin) based composite membrane that provides selective resistance for solutes while providing water permeability. The membrane may include optional additional functional additives in a crosslinked material matrix that provides 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.

Abstract: Described herein are protective coatings for reverse osmosis membranes comprising coating mixtures of graphene oxide crosslinked with copolymers. The crosslinked GO copolymer mixture coatings provide protection from chlorine-based defoulers of saline water and unprocessed fluids. The coated membranes described herein create a reverse osmosis structure that has excellent water flux and salt rejection. The crosslinking copolymers can comprise an optionally substituted vinyl imidazole constituent unit and an optionally substituted acrylic amide constituent unit.
