چکیده In the present research, amorphous UiO-66 and NH2-UiO-66 metal organic frameworks (aMOFs) were fabricated by typical solvothermal [1] method and the following ball milling process. After characterizing prepared aMOFs, they were inserted into polymer matrix containing polyethersulfone, polysulfone and polyvinylpyrrollidone with weight percent ratio of 40:40:20, respectively. The fabricated mixed matrix membranes (MMMs) were analysed by FT-IR, SEM, TGA, XRD and DSC techniques and their gas separation performances were also evaluated by constant volume/variabe pressure method in three upstream pressure of 3, 5 and 7. The best outcome was related to the MMM containing NH2-UiO-66 at 7 bar in which CO2 permeability and CO2/CH4 selectivity of 8.69 barrer and 75.56 were achieved, respectively.
