  • Ultrahigh-selectivity oxygen enrichment filled elastomeric silicone polymer membrane incorporating nanofillers
    Patent number: 7264650
    Abstract: A semipermeable separation element includes (a) a porous substrate, and (b) a film formed on the microporous substrate; the film comprising a silicone elastomer and a nanoparticle filler. The film preferably has an oxygen enrichment selectivity of at least 30, or even 60, over nitrogen. Methods of making and using the same and filter cartridges incorporating the same are also described.
