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.
