Ionic liquid assisted interfacial polymerization of β-Cyclodextrin into thin-film composite membranes for organic solvent nanofiltration

By direct introducing ionic liquid into the interfacial polymerization process of β-CD, the porous monomer based thin-film composite membranes are fabricated for efficient organic solvent nanofiltration with a high ethanol permeance of 57.01 L·m−2·h−1·MPa−1 and an ideal dye rejection rate of 99.98 %.
