  • Publication number: 20150047968
    Abstract: The present invention relates to the development and fabrication of thin-film polymer nanocomposites containing vertically aligned nanomaterials, such as single-walled carbon nanotubes (SWNTs). In certain embodiments, the present invention utilizes liquid crystal mesophases of hexagonally packed cylindrical micelles that orient with their long axes parallel to an applied magnetic field, thereby directing the alignment of the nanomaterials, such as SWNTs, sequestered in the micellar cores. In certain embodiments, the mesophase may be a stable, single-phase material containing monomers that can be polymerized after nanotube alignment to form the nanocomposite polymer.
