    摘要： Breathable non-wettable non-woven materials include a mass of melt-blown, non-woven fibers formed of a terpolymer of tetrafluroethylene, hexafluoropropylene and vinylidene fluoride monomers. Most preferably, the materials of the present invention are in the form of fabric structures which can be processed to form a variety of products for numerous end use applications, such as for garments, bandages, barrier vents, filter media and the like. In especially preferred form, the melt-blown non-woven fibers are comprised of a THV terpolymer formed of between about 30 to about 70 wt. % of teirafluoroethylene monomer, between about 10 to about 20 wt. % of hexafluoropropylene monomer, and between about 20 to about 65 wt. % vinylidene fluoride monomer.

    摘要： The present invention relates to hydrophilic membranes containing blends of polysulfone polymers and sulfonated polymers or copolymers, where the sulfonated polymers or copolymers are sulfonated before blending with the polysulfone polymer. The invention also relates to methods of preparing the hydrophilic membranes. In one aspect of the invention, the membranes are formed by casting a mixed polymer solution comprising a sulfone polymer and a copolymer of a sulfonated polymer and a sulfone polymer and quenching the film in an aqueous bath to produce a coagulated membrane. The membranes can be ultrafiltration or microfiltration membranes, symmetric or asymmetric.

    摘要： The present invention relates to oleophobic filtration media including polymeric membranes and other substrates that are coated with polymerized substituted or unsubstituted para-xylene. A method of coating such substrates with polymerized substituted or unsubstituted para-xylene is also provided. The coated substrates possess both hydrophobic (water repellent) and oleophobic (oil repellent) properties.
