  • Purified carbon nanotubes and applications thereof
    Patent number: 9799460
    Abstract: The present invention relates to a method of preparing purified carbon nanotubes (CNTs) comprising mixing starting CNTs with an organic solvent in the presence of sonication; substantially removing the organic solvent to obtain a CNT composition; and heating the CNT composition at 200° C. or higher to obtain the purified carbon nanotubes. The present invention further relates to the purified CNTs and cohesive CNT assemblies prepared from the method described herein, and articles (e.g. capacitor, energy storage device or capacitive deionization device) comprising the purified CNTs.
    Type: Grant
    Filed: October 5, 2015
    Date of Patent: October 24, 2017
    Assignee: YAZAKI CORPORATION
    Inventors: Yongan Yan, Nissim Ray
