  • Carbon nanotube composite materials
    Patent number: 8986576
    Abstract: A material consisting essentially of a vinyl thermoplastic polymer, un-functionalized carbon nanotubes and hydroxylated carbon nanotubes dissolved in a solvent. Un-functionalized carbon nanotube concentrations up to 30 wt % and hydroxylated carbon nanotube concentrations up to 40 wt % can be used with even small concentrations of each (less than 2 wt %) useful in producing enhanced conductivity properties of formed thin films.
    Type: Grant
    Filed: September 1, 2011
    Date of Patent: March 24, 2015
    Assignee: Sandia Corporation
    Inventors: Gregory O'Bryan, Jack L. Skinner, Andrew Vance, Elaine Lai Yang, Thomas Zifer
  • Method of making carbon nanotube composite materials
    Patent number: 8728566
    Abstract: The present invention is a method of making a composite polymeric material by dissolving a vinyl thermoplastic polymer, un-functionalized carbon nanotubes and hydroxylated carbon nanotubes and optionally additives in a solvent to make a solution and removing at least a portion of the solvent after casting onto a substrate to make thin films. The material has enhanced conductivity properties due to the blending of the un-functionalized and hydroxylated carbon nanotubes.
