  • High strength carbon nanotube plasma-treated fibers and methods of making
    Patent number: 9676630
    Abstract: Carbon nanotubes have excellent mechanical properties such as low density, high stiffness, and exceptional strength making them ideal candidates for reinforcement material in a wide range of high-performance composites. Fibers with increased tensile strengths are produced by employing plasma treatment under various conditions. Tensile strength is improved by at least 35%, relative to an untreated fiber. Methods of making such high strength carbon nanotube fibers via plasma processing are disclosed.
    Type: Grant
    Filed: May 28, 2013
    Date of Patent: June 13, 2017
    Assignee: THE UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF THE ARMY
    Inventors: Charles F. Cornwell, Charles P. Marsh, Charles R. Welch, Benjamin Ulmen, Dustin L. Majure

  • MESO-SCALE CARBON NANOTUBE SELF-ASSEMBLED TUBE STRUCTURES
    Publication number: 20130171401
    Abstract: Multiple-scale self-assembled tube structures (SATS) comprising multiwall carbon nanotubes (CNT) and processes for their nucleation and growth. These hierarchical and self-assembled SATS demonstrate the feasibility of controlled synthesis of macroscopic CNT structures and CNT-reinforced materials for use in broad applications such as structures, thermal transfer, electronics, fluid dynamics, and micro-fluidics.
