    Abstract: This patent is provided a method for producing a porous polymer film using vanadium oxide nanowires, and a porous polymer film obtained from the method. The method allows control of a uniform pore size and density through a simple process including the steps of: adding an ion exchanger to deionized water to perform acidification and adding a vanadate compound thereto to grow vanadium oxide nanowires by a sol-gel process; mixing the resultant solution of grown nanowires with a polymer solution to provide a mixed solution of nanowires; pouring the mixed solution of nanowires to a mold, followed by drying and curing, to form a film; and etching the resultant film with an etching solution to remove the vanadium oxide nanowires.

  • Publication number: 20150028247
    Abstract: A rigid polyurethane or polyisocyanurate foam includes 1 to 50 weight percent of a particulate poly(phenylene ether) having a mean particle size of 1 to 40 micrometers. The particulate poly(phenylene ether) imparts reduced flammability and reduced water absorption to the foam. The foam is useful as a thermally insulating material in articles including domestic appliances, building materials, tanks, pipelines, heating pipes, cooling pipes, cold stores, and refrigerated vehicles.

  • Patent number: 8933139
    Abstract: Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized A-B-A triblock copolymer resin and/or an A-B diblock copolymer resin into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form the gelatinous elastomer in-situ while simultaneously polymerizing the polyol and the isocyanate to form polyurethane foam. The polyurethane reaction is exothermic and can generate sufficient temperature to melt the styrene-portion of the A-B-A triblock copolymer resin thereby extending the crosslinking and in some cases integrating the A-B-A triblock copolymer within the polyurethane polymer matrix. The combination has a marbled appearance. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink. Another advantage of in situ gel-foam is that the gel component provides higher support factors compared to the base foam alone.

  • Patent number: 8933140
    Abstract: Combinations of gelatinous elastomer containing one or more phase change materials, known as “phase change gel”, and polyurethane foam may be made by introducing at least partially cured phase change gel particles comprising plasticized triblock copolymer resin and/or diblock copolymer resin and one or more phase change materials, into a mixture of polyurethane foam-forming components including a polyol and an isocyanate. The phase change gel can be crosslinked to form a cured gelatinous gel, which is then reduced in size before introduction. After the foam-forming components polymerize to make polyurethane foam, the phase change gel particles are discrete visible particles dispersed throughout the foam. The polyurethane reaction is exothermic and can generate sufficient temperature to at least partially melt the styrene-portion of the triblock copolymer resin thereby extending the crosslinking.

  • Publication number: 20140371338
    Abstract: The shelf life of polyurethane polyol pre-blends containing halogenated olefins is extended by encapsulation of active components such as catalysts and/or surfactants. The active component is encapsulated in a crystallizable or thermoplastic polymer. The encapsulated particles have a size of 2,800 microns or less and the active components are not significantly leaked out, particularly in the presence of halogenated olefins.
