Studies of blends of topologically distinct samples of the polymer of intrinsic microporosity PIM-1 provide, for the CO2/N2 gas pair, insight into the optimum loop topology required for high selectivity and permeance of thin film composite (TFC) membranes.

In this work, PIM-1 thin film composite membranes supported on PAN were developed. The influence of PIM-1 concentration and nature of solvent stabilizer on the structure and gas separation properties of TFC membranes were studied. It was shown that amylene stabilized chloroform as PIM-1 solvent allows membranes to be obtained with a uniform selective layer in the whole range of concentrations used, and the ethanol stabilized chloroform provides a uniform layer at 2 and 4 wt % PIM-1 concentration. The best CO2/N2 selectivities were 35,9 and 39,5 for 4 % wt PIM-1 solution in ethanol and amylene stabilized chloroform, respectively.
