Patents by Inventor Christopher Kloxin

Christopher Kloxin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Radio frequency magnetic field responsive polymer composites
    Patent number: 9044902
    Abstract: The invention includes a composite material comprising magnetic field responsive particles distributed in a reversibly crosslinked polymer, wherein the reversibly crosslinked polymer includes thermally reversible bonds. In one embodiment, exposing the composite material to an electromagnetic field allows for crack-healing, remolding and/or bonding of the material.
    Type: Grant
    Filed: November 23, 2011
    Date of Patent: June 2, 2015
    Assignee: The Regents of the University of Colorado, a Body Corporate
    Inventors: Christopher Bowman, Brian Adzima, Christopher Kloxin
  • Stress relief for crosslinked polymers
    Patent number: 8877830
    Abstract: The invention provides methods for inducing reversible chain cleavage of polymer chains in a crosslinked polymeric material or during polymerization of a polymeric material. Reversible cleavage of the polymer backbone is capable of relieving stress in the polymeric material as the bonds reform in a less stressed state. The invention also provides mixtures for making crosslinked polymeric materials, methods for making polymeric materials capable of reversible chain cleavage, materials made by the methods of the invention, and linear monomers containing reversible chain cleavage groups which are useful in the materials and methods of the invention. The mixtures of the invention may be dental restorative compositions used for forming dental restorative materials.
