Effects of hydrolyzed PIM-1 in polyimide-based membranes on C2–C4 alcohols dehydration via pervaporation

Polymers of intrinsic microporosity, specifically PIM-1, have attracted significant attention for gas separation due to its relatively high permeability and reasonably good selectivity. Although few studies evaluated the potential of PIM-1 in pervaporation, their dehydration performance was not impressive because of low selectivity. In this work, we aim to develop a simple but effective approach to enhance the selectivity of PIM-1 while...
