Title: Effect of zeolitic imidazolate frameworks on the gas transport performance of ZIF8-poly(1,4-phenylene ether-ether-sulfone) hybrid membranes
Authors: Díaz, Kenya1, López-González, Mar2 mar@ictp.csic.es, del Castillo, Luis F.1 lfelipe@unam.mx, Riande, Evaristo2
Source: Journal of Membrane Science. Nov2011, Vol. 383 Issue 1/2, p206-213. 8p.
Subjects: Zeolites, Sulfones, Polyethers, Glass transition temperature, Artificial membranes, Diffusion, Ethylene
Abstract: Abstract: This work reports the permeability of hydrogen, nitrogen, oxygen, carbon dioxide, methane, ethane and ethylene across ZIF-8/poly(1,4-phenylen ether-ether-sulfone) hybrid membranes containing 0, 0.10, 0.20 and 0.30 weight fractions of ZIF-8. The glass transition temperature is independent on the filler content suggesting that the filler does not affect the polymer chains mobility. The study was carried out at 1bar in the range of 283–313K and the diffusion coefficient of the gases was obtained in this range of temperature by means of the lag time method. The permeability and diffusion coefficients obey Arrhenius behavior and the activation energies associated with this processes were obtained from the slopes of the respective plots. The performance of the membranes as determined by the closeness of their selectivity to the Robeson''s upper bounds increases as the ZIF-8 content of the hybrid membranes increases. The membrane with 30% (w/w) content exhibits at 303K pretty good selective properties for O2/N2 and H2/N2. The selectivity for C2H4/C2H6 is of the order of 3 with P(C2H4)≅3Barrer. Extrapolation of the permeability data for H2/N2 at high temperatures gives a selectivity that coincides with that predicted by the Robeson limit for this pair of gases. [Copyright &y& Elsevier]
