  • Patent number: 8448334
    Abstract: A process for remediating the insulating properties of magnet wire insulation is described. Magnet wire, used in electric motors and other electrical devices, comprises an electrically-conductive core covered by a thin insulating layer. The insulating layer may be damaged or compromised during manufacture or service. A process for incorporating polymerizable materials, sequestered in microcapsules, within the insulating layer is described. When the insulating layer is subjected to conditions sufficient to compromise its insulating character, the microcapsules fracture and release their contents which then polymerize and re-establish the insulating properties of the layer.

  • Publication number: 20120247666
    Abstract: A method of forming an adhesive bond between a first substrate and a second substrate includes applying a semi-crystalline polymeric adhesive composition to a bonding area of the first substrate, and, after applying, disposing the second substrate adjacent to and in contact with the composition to form a workpiece. After disposing, the method includes heating the workpiece to cure the composition and thereby form a thermoset polymeric adhesive material that is crosslinked. After heating, the method includes cooling the workpiece such that the material has a crystalline molecular structure. Concurrent to cooling, the method includes imposing a stress on the material to thereby orient the crystalline molecular structure in a desired direction, and, after imposing, dissipating the stress along the crystalline molecular structure in the desired direction to thereby form the adhesive bond between the first substrate and the second substrate.

  • 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.

  • 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.

  • Publication number: 20100092790
    Abstract: Hybrid articles comprising a molded mixture of a light metal alloy and a polymer are formed by processing (including co-molding and co-extruding) the metal in a semi-solid state at a high shear rate and the polymer in a melt processable state. For example, magnesium alloy particles in a thixotropic condition are mixed with particles or globules of the polymer and molded into a hybrid metal-containing and polymer-containing body. The proportions of magnesium and polymer may be varied substantially depending on the desired properties of the hybrid article. In another embodiment the light metal and polymer may be co-extruded as two or more distinct layers into a solid or hollow hybrid body.
