Addition of nanoparticles to high free volume, stiff chain, glassy polymers can increase light gas (CO2, hydrogen, nitrogen, and methane) permeability with increasing particle loading. Polymer-particle interactions influence the maximum practical particle loading. In this case, light gas diffusivity increases over an order of magnitude relative to that in the unfilled polymer. Polymer-penetrant interactions have a strong influence on gas transport. There are also possibilities for reactions between the particle and penetrants as well. A discussion covers the influence of mineral nanoparticle dispersion on permeability, diffusivity, and solubility in high free volume, stiff chained, glassy polymers; particle dispersion; polymer-particle and penetrant-particle reactions; and the complexity and versatility of mineral filled nanocomposite materials. This is an abstract of a paper presented at the 2006 AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
