Fabrication of Graphene-based Membranes for Solvent-resistant Nanofiltration

Solvent-resistant nanofiltration (SRNF) is a promising technology which developed rapidly in recent years, which exhibits broader application prospects in separation of industries organic solvent system. Among various materials used for SRNF-membranes, graphene-based nanomaterials have aroused great interests due to the unique molecular sieve properties and excellent tolerance to organic solvents and harsh chemical environments. This paper emphatically introduces the progresses of membrane preparation with graphene-based nanomaterials for SRNF and their application in separation processes. The performances including permeability and stability of different kinds of graphene-based SRNF membranes in the process of filtration are also evaluated and discussed. (paper)
