Researchers develop novel antifouling nanofiltration membranes using ionic liquid

A new post-modification strategy has been proposed by a research group led by Prof. Wan Yinhua from Institute of Process Engineering (IPE) of the Chinese Academy of Sciences, aiming to achieve high separation selectivity and strong fouling resistance of nanofiltration (NF) membranes. The strategy involves polyamide swelling rearrangement induced by ionic liquid (IL), which facilitates polyelectrolyte deep grafting. The study was published in the AIChE Journal.
