Non-ionic deep eutectic solvents for membrane formation

Deep eutectic solvents (DES) have recently emerged as a new class of inexpensive biodegradable and additives with diverse applications. In this study, family non-ionic deep (NIDES) is proposed for the first time membrane preparation. Three types NIDES, N-methylacetamide-acetamide (DES-1), N-methyl acetamide-N-methyl urea (DES-2), acetamide-N,N′-dimethyl (DES-3) were synthesized used to dissolve polyvinylidene fluoride (PVDF) polymer. The effects additive polyvinylpyrrolidone (PVP) type NIDES on PVDF characteristics, water permeability bovine serum albumin (BSA) separation studied. membranes prepared DES-1 2 wt% PVP exhibited good permeate flux (96.82 L/m2.h) high BSA factor (96.32%). High performance can thus be efficiently using NIDES.
