  • Method for functionalizing nanotubes and improved polymer-nanotube composites formed using same
    Patent number: 8404775
    Abstract: A polymerizable ligand comprising, in one embodiment, a polyaromatic compound, with a terminal functional group, non-covalently bonded to the sidewalls of carbon nanotubes. This structure preserves the structural, mechanical, electrical, and electromechanical properties of the CNTs and ensures that an unhindered functional group is available to bond with an extended polymer matrix thereby resulting in an improved polymer-nanotube composite.
    Type: Grant
    Filed: November 15, 2010
    Date of Patent: March 26, 2013
    Assignee: The Johns Hopkins University
    Inventors: Jennifer L. Sample, Amy A. Hofstra
