Patents Assigned to ZYVEX PERFORMANCE MATERIALS
  • Patent number: 9828473
    Abstract: Methods and compositions are provided for the efficient and beneficial use of nanoparticulates, such as carbon nanotubes. In various embodiments, a nanoparticulate entrapped in a linear polymer, where the linear polymer is formed in the presence of the nanoparticulate, is provided. The entrapped nanoparticulate provides an efficient means to introduce nanoparticulates into compositions, such as resins and fiber-reinforced resins, allowing for increased dispersion and beneficial properties.

  • Publication number: 20120259073
    Abstract: Poly(aryleneethynylene) polymers for exfoliating and dispersing/solubilizing nanomaterial are provided herein. The poly(aryleneethynylene) polymers have unit monomer portions, each monomer portion having at least one electron donating substituent thereby forming an electron donor monomer portion, or at least one electron withdrawing substituent thereby forming an electron accepting monomer portion. Such polymers exfoliate and disperse nanomaterial without presonication of the nanomaterial.

  • Publication number: 20100009165
    Abstract: Methods for making multifunctional nanomaterial-containing composites that include the incorporation of nanomaterials into such composites in at least one of two manners: 1) in a solution of dispersed nanomaterials for coating onto a substrate; and 2) by dispersing nanomaterials in a matrix material, such as epoxy, applied to a single substrate layer or sandwiched between adjacent layers in a multiple layer composite. According to such methods, a high loading of nanomaterials may be incorporated into the composites without any deterioration in processing or handling properties.

  • Patent number: 7547472
    Abstract: A new, non-wrapping approach to functionalizing nanotubes, such as carbon nanotubes, in organic and inorganic solvents is provided. In accordance with certain embodiments, carbon nanotube surfaces are functionalized in a non-wrapping fashion by functional conjugated polymers that include functional groups. Various embodiments provide polymers that noncovalently bond with carbon nanotubes in a non-wrapping fashion. For example, various embodiments of polymers are provided that comprise a relatively rigid backbone that is suitable for noncovalently bonding with a carbon nanotube substantially along the nanotube's length, as opposed to about its diameter. In preferred polymers, the major interaction between the polymer backbone and the nanotube surface is parallel ?-stacking. In certain implementations, the polymers further comprise at least one functional extension from the backbone that are any of various desired functional groups for functionalizing a carbon nanotube.
