  • Publication number: 20140051812
    Abstract: A method for oxidizing polymeric surfaces to render them hydrophilic and more amenable to wetting is disclosed. The method comprises reacting the surface of a hydrophobic polymer with a peracid, especially Caro's acid, under conditions effective to render the surface more hydrophilic. Although strong oxidants can easily carbonize or discolor the surface of organic polymers, polymers can be rendered more hydrophilic without these problems when process conditions are carefully controlled. Specifically, treatment of the polymer surface with a peracid such as Caro's acid requires judicious selection of oxidation temperature, acid concentration, and peroxide content to achieve reaction rates that provide the desired level of hydrophilicity without charring or otherwise damaging the polymer.

    Abstract: A polysulfone is provided with a nitrogen-containing functional group having an affinity to an acid, an electrolyte membrane using the polysulfone, and a fuel cell including the electrolyte membrane. In particular, the polysulfone includes a nitrogen-containing functional group that has an affinity to an acid, such as a phosphoric acid, thereby having an excellent acid retaining ability. In an electrolyte membrane including the polysulfone and an acid, the amount of the retained acid can be controlled. Therefore, the electrolyte membrane has a high ionic conductivity and a high mechanical strength. A polysulfone blend of polysulfone and a thermoplastic resin prevents the dissolution of polysulfone by phosphoric acid, so that an electrolyte membrane using the polysulfone blend has an improved durability. A cross-linked reaction product of polysulfone, a cross-linking agent and a polymerization product of polysulfone, a thermoplastic resin, and a cross-linking agent strongly resist a phosphoric acid.

  • Patent number: 7258904
    Abstract: According to the present invention, a water absorbent material and materials to be sucked included in a water permeable bag type member form a water absorber. Thus, the water absorber is small both in weight and volume upon its transportation, and accordingly, the water absorber can be rapidly conveyed in large quantities without depending on a human power. The water absorber absorbs water upon its use to adequately satisfy a function of a form traceability for weight, volume and outline.

  • Patent number: 7176175
    Abstract: A cleansing processing agent that is able to remove harmful substances contained in a variety of waste materials and a cleansing method are disclosed. Specifically, there is disclosed a cleansing processing agent containing a polymer having at least one of styrene or conjugate diene and acrylonitrile as constituent unit and into which are introduced ionic groups. This cleansing processing agent is contacted with a material for processing containing harmful substances contained in the material for processing for removing the harmful substances. The waste plastics can be used effectively, while a modified product obtained on chemical modification of the plastics is useful for suppressing environmental destruction caused by leakage of the harmful substances contained in the waste materials.

  • Patent number: 7160927
    Abstract: Porous matrices and membrane matrices comprising sulfonated aryl sulfonate polymers are prepared from a sulfonated aryl sulfonate polymer solution which is made by dissolving an aryl sulfonate polymer, and optionally a polymer other than aryl sulfonate, in a sulfonating acid solvent such as sulfuric acid. The solutions are then cast as wet films from which the matrices are coagulated. By controlling composition and process parameters, hydrophilic matrices of varying morphology are produced.
