摘要: Design and fabrication of thin film nanocomposite (TFN) membranes with tunable solvent permeation properties is highly required to meet the demands practical applications. Herein, a series TFN are elaborately fabricated by embedding cyclodextrins (CDs) into hydrophilic polymeric membrane (e.g., polyethylenimine, PEI). Within active layer, hydrophobic cavities CDs serve as exquisite pathways for nonpolar solvents, whereas free volume PEI matrix act efficient polar constructing dual-pathway nanostructure. The these two can be accurately tuned adjusting cavity size CD fractional (FFV) PEI. Increasing allows larger permeate, meanwhile increasing flux. For instance, varying from 0.60 0.75 nm elevates toluene (0.60 nm) permeance 0.13 2.52 L m–2 h–1 bar –1. Similar behaviors observed f...
