Abstract

A new nanocomposite family was discovered utilizing rubbery polymers as the matrix. Like the stiff chain polymers, permeability of light gas, i.e., CO2, H2 , N2, and CH4, and diffusivity increased with increasing particle loading filled with 34 vol % MgO was 2600% higher than the unfilled polymer. The change in permeability and diffusivity depended on particle dispersion, which was closely related to particle-polymer interactions. However, depending on particle surface chemistry and penetrant-particle interactions, penetrant solubility may also be enhanced. These studies focused on both polar and non-polar polymers, as well as a series of particles. These materials were characterized using light gas sorption and permeation to monitor gas transport properties as well as AFM and X-ray microtomography to characterize particle distribution within the polymer matrix. This is an abstract of a paper presented at the 2006 AIChE National Meeting (San Francisco, CA 11/12-17/2006).
