  • Purification of carbon nanotubes via selective heating
    Patent number: 10333069
    Abstract: The present invention provides methods for purifying a layer of carbon nanotubes comprising providing a precursor layer of substantially aligned carbon nanotubes supported by a substrate, wherein the precursor layer comprises a mixture of first carbon nanotubes and second carbon nanotubes; selectively heating the first carbon nanotubes; and separating the first carbon nanotubes from the second carbon nanotubes, thereby generating a purified layer of carbon nanotubes. Devices benefiting from enhanced electrical properties enabled by the purified layer of carbon nanotubes are also described.
    Type: Grant
    Filed: November 17, 2016
    Date of Patent: June 25, 2019
    Assignees: The Board of Trustees of The University of Illinois, Northwestern University, University of Miami
    Inventors: John A. Rogers, William L. Wilson, Sung Hun Jin, Simon N. Dunham, Xu Xie, Ahmad Islam, Frank Du, Yonggang Huang, Jizhou Song
