  • Patent number: 10682614
    Abstract: A porous membrane may be manufactured with a high content of filler material and a polymer binder. After forming the membrane, the membrane may be post processed to reform the polymer binder into a stronger yet still porous membrane. The post processing may include bringing the membrane above the melt temperature of the polymer or by immersing the membrane in a solvent. Photomicrographs show that the structure may change, yet the performance of the material in batteries and other electrochemical cells may remain the same or even improve.

  • Patent number: 9145492
    Abstract: The method to produce ultra-high-molecular-weight polyethylene (UHMWPE) incorporates tungsten-doped titania (TiO2/W) nanofiller during the ethylene polymerization process. The UHMWPE possesses improved mechanical and thermal properties. The process for producing the UHMWPE includes contacting ethylene under polymerization conditions with a polymerization catalyst (a vanadium (III) complex bearing bidentate salicylaldiminato ligands) in the presence of TiO2/W nanofiller and a co-catalyst in a reactor. The reactor is charged with solvent (e.g., toluene) and heated to a temperature suitable for polymerization, e.g., about 30° C. Following heating, the ethylene monomer is fed into the reactor and allowed to saturate for at least 10 minutes, and a methyl aluminum dichloride co-catalyst (MADC) is added to initiate polymerization of ethylene. Polymerization is quenched by adding methanol containing HCl incorporated with titania-tungsten nanofillers, which is then washed and dried to yield UHMWPE.

  • Publication number: 20140170398
    Abstract: A light-weight material and a method for producing a light-weight material use removable forms to produce an array of interconnected voids within the material. The forms include a plurality of spaced apart and adjoining blocks onto which the material is deposited, and the blocks are constructed of a material that may be desolidified, such as by vaporization, to remove the blocks from the material, leaving behind a network of interconnected voids.

  • Publication number: 20140154495
    Abstract: The present invention relates to a defect inspection apparatus including: a container storing a fluid; a passage member that is configured such that a hollow fiber membrane travel passage, which allows the porous hollow fiber membrane to pass therethrough continuously, is formed thereinside and the passage member being disposed in the fluid to thereby fill the passage with the fluid; a restrictor that restricts travel of the porous hollow fiber membrane such that the porous hollow fiber membrane passes through the fluid in the hollow fiber membrane travel passage of the passage member; a fluid suction device that flows the fluid in the hollow fiber membrane travel passage to thereby lower the pressure of the fluid in the hollow fiber membrane travel passage; and an air bubble detector that detects an air bubble that is released into the fluid from a defect of the porous hollow fiber membrane.

  • Publication number: 20140141581
    Abstract: Particles having a property of absorbing carbon at a particular temperature or higher are deposited on a graphene. The particles are heated to a temperature equal to the particular temperature or higher to make the particles absorb carbon from portions of the graphene under the particles. The particles are removed. Consequently, a graphene nanomesh is obtained.

  • Publication number: 20140137399
    Abstract: The present invention provides a method for producing a separator for nonaqueous electrolyte electricity storage devices. The method allows: avoidance of use of a solvent that places a large load on the environment; and relatively easy control of parameters such as the porosity and the pore diameter. The production method of the present invention includes the steps of: preparing an epoxy resin composition containing an epoxy resin, a curing agent, and a porogen; forming a cured product of the epoxy resin composition into a sheet shape or curing a sheet-shaped formed body of the epoxy resin composition, so as to obtain an epoxy resin sheet; removing the porogen from the epoxy resin sheet by means of a halogen-free solvent so as to form a porous epoxy resin membrane; and drying the porous epoxy resin membrane by heat-roll drying.
