Title : High-performance forward osmosis membranes achieved by incorporating two-dimensional nanomaterials
Abstract:
Forward osmosis technology has been widely applied in industrial areas including desalination and wastewater treatment. However, the forward osmosis membrane is still facing challenges such as the trade-off between selectivity and permeability, membrane fouling and internal concentration polarization. Enhanced forward osmosis membrane performance could be achieved by embedding nanomaterials and intelligent design of advanced nanocomposite membranes. In our recent studies, we have explored different two-dimensional nanomaterials such as graphene oxide and MXene for improving the performance and properties of forward osmosis membranes. In addition, we have designed different membrane modification strategies for forward osmosis membrane modification. We report here how the incorporation of two-dimensional nanomaterials improves the filtration efficiency of forward osmosis membranes and show proof-of-concept studies about applying these advanced FO membranes in desalination, sewage concentration, wastewater treatment, and some emerging application areas such as organic solvent recovery and cooling water production in the CO2 capture system.
