Carbon nanotube composite materials

DWPI Title: Matrix material, comprises essentially of vinyl thermoplastic polymer, unfunctionalized carbon nanotubes and hydroxyllated carbon nanotubes dissolved in solvent
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.
Use: Matrix material.
Advantage: The material has excellent coating properties such as high durability, solvent resistance, and low creep, while maintaining solution processability for casting thin films of composite materials. The material has improved electrical properties.
Novelty: A matrix material comprises essentially of vinyl thermoplastic polymer, unfunctionalized carbon nanotubes and hydroxyllated carbon nanotubes dissolved in a solvent, where the unfunctionalized carbon nanotubes comprise a concentration of greater than 0 wt.% and up to approximately 30 wt.%, and the hydroxylated carbon nanotubes comprise a concentration of greater than 0 wt.% and up to approximately 10 wt.%.
