Separation and flux performance were compared in graphene-based membranes that differed only in the method of deposition of reduced graphene oxide platelets. Membranes with higher degree of order were produced by evaporation-induced capillary-force self-assembly, which showed higher steric rejection properties while simultaneously accentuating water permeance compared to membranes produced by the traditional vacuum filtration technique. These studies attempt to establish structure–property correlations in graphene-based membranes.
