Reverse osmosis (RO) has attracted wide attention for its extensive applicability in brackish water and seawater desalination. Thin-film composite (TFC) polyamide (PA) RO membranes consisting of a dense separating layer and a porous support layer have been the leading products of this field. However, relatively low permeability-selectivity of PA RO membrane and membrane fouling of TFC RO membrane limit the widespread applicability of TFC PA RO membranes.
