Mixed Matrix Membranes
zeolitic imidazolate frameworks
Zeolitic imidazolate framework-93 (ZIF-93) continuous membranes were synthesized on the inner side of P84 co-polyimide hollow fiber supports by microfluidics. MOFs and polymers showed high compatibility and the membrane exhibited H-2-CH4 and CO2-CH4 separation selectivities of 97 (100 degrees C) and 17 (35 degrees C), respectively.
