Nonporous metal oxide nanoparticles (primary particle diameter as low as 2.5 nm) have been dispersed in rubbery polymer to make membranes that have over an order of magnitude higher light gas (i.e., CO2, N2, O2, H2) permeability with little or no change in selectivity relative to the neat polymer, which runs counter to traditional filled rubbery polymers. For example, the CO2 permeability was 1100 barrers in filled 1,2-butadiene as compared to 52 barrers for the unfilled polymer. For both materials, the CO2/N2 selectivity was 14, at 35°C and 3.4 atm. Nanoparticle filled poly(ethylene oxide) membranes reached permeabilities as high as 1700 barrer while maintaining a CO2/N2 selectivity of 25, at 35°C and 3.4 atm. The degree of permeability enhancement is particle loading dependent, with maximum particle loading over 50 wt % for some materials. This is an abstract of a paper presented at the AIChE Annual Meeting and Fall Showcase (Cincinnati, OH 10/30/2005-11/4/2005).
