چكيده فارسي :
Nanocomposite membranes of polydimethylsiloxane (PDMS) with different amounts of fumed silica were synthesized over a porous support of polyacrylonitrile. The prepared membranes were characterized using atomic force microscopy and thermal gravimetric analysis. AFM results indicated the nanoscale dispersion of silica particles in polymer matrix. Permeation of methane and n-butane single gases at different upstream pressures were studied. The results showed that the nanocomposite membrane exhibited increase in permeability and simultaneously increase in selectivity
