英文摘要amino modified multi-walled carbon nanotubes (mwnts-nh2) were incorporated into poly(amide-6-b-ethylene oxide) (pebax 1657) to prepare mixed matrix membranes (mmms). the permeation properties of co2, n-2, ch4 and h-2 were studied and the physical properties of pebax/mwnts-nh2 mmms were characterized by x-ray diffractometer (xrd), fourier transform infrared (ftir) and scanning electron microscopy (sem). the incorporation of mwnts-nh2 increased the amorphous region of pebax phase in pebax/mwnts-nh2 mmms, which was beneficial for the improvement of gas permeabilities. the apparent activation energy for permeation (e-p) for co2 decreased with the increase of pressure, while those for n-2, ch4 and h-2 almost did not change. the e-p for co2, n-2, ch4 and h-2 slightly decreased with the incorporation of mwnts-nh2. compared with pristine pebax membrane, co2 permeability increased almost 3 times for pebax/mwnts-nh2 mmms with 33 wt% mwnts-nh2. with the increase of mwnts-nh2 content, the normalized permeabilities of n-2, ch4 and co2 showed almost the same increment and the selectivities of co2/n-2, co2/h-2 and co2/ch4 remained constant, which were consistent with the maxwell model prediction. thus, the incorporation of mwnts-nh2 significantly improved the gas permeation properties of pebax/mwnts-nh2 mmms.
