Thin-film composite hollow fibre membrane for low pressure organic solvent nanofiltration

, 2020
Polyamide thin film membranes have shown outstanding performance in organic solvent nanofiltration (OSN). However, it is still challenging to produce polyamide hollow fibres for OSN, mainly due to limited solvent resistance of hollow fibre substrates and

Cellulose membranes for organic solvent nanofiltration [PDF]

Journal of Membrane Science, 2018
Abstract Cellulose membranes were fabricated by phase inversion from solutions of cellulose in 1-ethyl-3-methylimidazolium acetate ([EMIM]OAc) as solvent and acetone as volatile cosolvent. The rejection of Bromothymol Blue (624 Da) in ethanol increased and the permeance decreased by increasing the cellulose concentration in the solution prior to ...

Molecular‐Level Pore Engineering for Precise Separation via Active Solvent‐Mediated Interfacial Polymerization

Advanced Science, EarlyView.
We demonstrate that microemulsion solvents can actively template molecular‐level pores within selective layer during interfacial polymerization. By creating localized quasi‐homogeneous polymerization zones, the membrane achieved a 7.1‐fold enhancement in water permeance with increased selectivity.
