Importance of small loops within PIM-1 topology on gas separation selectivity in thin film composite membranes

Abstract
Studies of blends of topologically distinct samples of the polymer of intrinsic microporosity PIM-1 provide, for the CO_{2} gas pair, insight into the optimum loop topology required for high selectivity and permeance of thin film composite (TFC) membranes.
