  • Materials and methods for retarding or preventing thermal runaway in batteries
    Patent number: 8951654
    Abstract: One embodiment includes a rechargeable charge storage device including a microcapsule disposed within said rechargeable charge storage device; and a thermal retardant chemical species contained within said microcapsule, wherein said microcapsule is adapted to release said chemical species upon being exposed to a triggering event either prior to or during an unstable rise in temperature of said charge storage device.
    Type: Grant
    Filed: December 2, 2011

  • Fuel cell assembly
    Patent number: 7972744
    Abstract: A composite electrolyte membrane for a fuel cell is disclosed. The membrane is formed of a polymer having layers of a clay-based cation exchange material. The substrate comprises an electrode formed from a solution that has an exfoliated, inorganic, sodium-based cation exchange material, an ionically conductive polymer-based material, and a solvent-dispersant.

  • Method for forming nanocomposite materials
    Patent number: 7737211
    Abstract: A method for forming a nanocomposite material includes introducing a nanofiller material having polar end groups into an extruder having a polymeric material therein. An unsaturated shielding material is introduced into the extruder. The unsaturated shielding material reacts with the polar end groups, thereby forming a shielded nanofiller material. The shielded nanofiller material is grafted to the polymeric material, thereby forming the nanocomposite material. The nanofiller material therein is substantially exfoliated, and the nanocomposite material exhibits enhanced physical properties.

  • Multi-layer nanocomposite materials and methods for forming the same
    Publication number: 20100098925
    Abstract: A multi-layer nanocomposite material includes a first layer of a first polymeric material and a second layer of nanocomposite material. The nanocomposite material includes a second polymeric material and a nanofiller material exfoliated therewithin. The second layer is established on the first layer, or the first layer is established on the second layer. The multi-layer nanocomposite material exhibits enhanced physical properties and enhanced ductility due to the improved stress dissipation of the secondary layers during impact.

  • Method for making nanocomposite materials
    Patent number: 7462666
    Abstract: A method for making a nanocomposite material includes introducing a solution including a nanofiller material and a supercritical fluid into a molten polymeric material within an extruder. The supercritical fluid is caused to substantially instantaneously convert to a gas phase, thereby forming the nanocomposite material having the nanofiller material substantially homogeneously dispersed therein.
