Abstract: A polymeric porous substrate is described. The substrate may be used as battery separator or in other industrial applications. The polymeric porous substrate is formed from a polymer such as a polyimide or polyetherimide that, in the absence of porous particles, forms a skin when cast into a substrate. The polymeric porous substrate also includes porous particles.

Abstract: The present invention includes a method, composition and apparatus for forming a nanoparticle filled polymer having similar gas selectivity and greater gas permeability than the native polymer. The nanoparticle filled polymer includes one or more polymeric materials and one or more nanoparticles dispersed within the one or more polymeric materials that increasing the permeability of the nanoparticle filled polymers relative to the permeability of the native polymer membrane.

Abstract: This invention relates to polyolefin alloys that are receptive to metal plating. These compositions also have enhanced properties and are easily processed into articles by various molding methods. The blends of the invention preferably include a polyethylene component, acrylonitrile-butadiene-styrene polymer(s), and at least one styrene monoolefin copolymer. The invention also relates to articles containing such alloys, and to methods of forming such blends and articles containing the same. These blends have excellent platability and superior physical properties including enhanced stiffness and toughness.
