A new design for nanofiber interlayer supported forward osmosis composite membranes

Forward osmosis (FO), an emerging membrane-based technology, offers low energy consumption and low membrane fouling potential, but the lack of high-performance FO membranes hinders the large-scale application of FO. Generally, an ideal high-performance FO membrane should have high water permeability, low salt permeability, low structural parameter (S value), excellent antifouling performance, and stable chemical properties. Among them, nanofiber-supported FO membranes have gained popularity.
