    in this study a series of mixed matrix membranes were prepared comprising poly-sulfone by poly-ethylene glycol mixed matrix and ordered graphene hydroxyl nanoparticles as filler with loadings varying between 1 and 3wt %. the interaction between the filler and the polymer was studied by scanning electron microscopy and permeability analysis for co2, ch4. the gas permeation fluxes of the derived nanocomposite membranes are increased nearby 69% in mixed matrix membrane with 10wt % peg introduced. according to permeability and selectivity results derived from gas separation tests, the membrane with 1wt % graphene hydroxyl nanoparticles have stronger interaction with psf (ppg-10-1) which can increase the permeability of gases could increase selectivity of co2/ch4.
