Highly-permselective NF membranes are critical to energy-efficient ionic separation. Herein, an ultra-permselective polyamide (PA) nanofilm with asymmetric two-layered structure is achieved by supramolecular chemistry modulated interfacial polymerization (IP) process. Such nearly-40-nm asymmetric PA...
