Polar Pore Surface of Polyamide Membranes Enabling Efficient Solvent Mixture Separation

open access: yesAdvanced Functional Materials, EarlyView.
A polyamide membrane with polar pore surfaces and relatively large pore is fabricated through interfacial polymerization between polyethyleneimine and trimesoyl chloride. Rapid separation of solvents with polarity differences is achieved by the synergistic effects of pore polarity and size sieving.
