“…The stable ionic cross-linking structure of PECN membranes is conducive to the continuous preparation of high-purity organic solvents. Indeed, the cross-linked sulfated PECN hollow fibre membrane showed a stable separation performance in fusel oil dehydration [77] , and the organic content in feed was enriched from 90 to 99 wt% in 36 h (initial 1000 g fusel oil, membrane area 56.5 cm 2 , 50 °C). Furthermore, sulfated PECN membranes with controlled thickness and pore size were fabricated via self-assembly and vacuum filtering [55] .…”
