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.
Claims21
A material consisting essentially of a vinyl thermoplastic polymer, un-functionalized carbon nanotubes and hydroxylated carbon nanotubes dissolved in a solvent,
- wherein said un-functionalized carbon nanotubes comprise a concentration of greater than 0 wt % and up to approximately 30 wt %, and wherein said hydroxylated carbon nanotubes comprise a concentration of greater than 0 wt % and up to approximately 10 wt %.
A material consisting essentially of a vinyl thermoplastic polymer, un-functionalized carbon nanotubes, hydroxylated carbon nanotubes and an additive dissolved in a solvent,
- wherein said un-functionalized carbon nanotubes comprise a concentration of greater than 0 wt % and up to approximately 4 wt %, and wherein said hydroxylated carbon nanotubes comprise a concentration of greater than 0 wt % and up to approximately 40 wt %.
A nanocomposite material comprising a non-conductive vinyl thermoplastic polymer, un-functionalized carbon nanotubes, hydroxylated carbon nanotubes, and an optional additive,
- wherein said un-functionalized carbon nanotubes comprise a concentration of greater than 0 wt % and up to approximately 4 wt %, and wherein said hydroxylated carbon nanotubes comprise a concentration of greater than 0 wt % and up to approximately 10 wt %.
