Three phase Pebax^? MH 1657/PEG-ran-PPG/CuBTC（polymer/liquid/solid） was successfully deposited as a selective layer on a porous Polysulfone（PSF） support. In fact, the beneficial properties of PEG（high selectivity） with those of PPG（high permeability, amorphous） have been combined with superior properties of mixed matrix membrane（MMMs）. The membranes were characterized by DSC, TGA and SEM, while CuBTC was characterized by CO₂ and CH₄adsorption test. Statistically b...
