  • GAS SEPARATION MEMBRANES AND PROCESSES FOR THE MANUFACTURE THEREOF
    Publication number: 20100313752
    Abstract: The present invention relates to gas separation membranes for separating carbon dioxide from other gas species, polymer compositions suitable for this application, and processes for the manufacture thereof. In particular, the present invention relates polymeric compositions comprising a host polymer that is permeable to the targeted gas species, such as carbon dioxide and has a selectivity for the target gas species over other gas species. The polymeric composition also comprises domains of a polymeric material that are, for example at least 0.5 nm in diameter and that have a higher permeability for the targeted gas compared to the host polymer. The present invention can provide membranes that have a permeability and selectivity above the Robeson's upper bound.
