“…1–4 However, due to the “trade-off” effect, membranes often must be prepared at the expense of permeate flux to achieve high selectivity, and vice versa . 5 Hydrophilic modifications of membrane surfaces, 6–8 optimisation of the interfacial polymerisation processes, 9,10 construction of asymmetric membrane structures 11,12 and modulation of the two-dimensional (2D) membrane d -spacing 13,14 have proven useful in breaking the upper limit of the membrane “trade-off”, but there is still a large gap between these methods and the desired effects. In addition, membrane fouling affects the selectivity and permeability of membranes.…”
