  • Dispersion comprising carbon nanotubes and graphene platelets
    Patent number: 9868875
    Abstract: A preferably aqueous dispersion comprises carbon nanotubes and graphene platelets, with the ratio by mass of carbon nanotubes to graphene platelets being situated within a range from ?5:95 to ?75:25. In a process for preparing a dispersion of this kind, carbon nanotubes and graphene platelets are combined so that the ratio by mass of carbon nanotubes to graphene platelets in the dispersion is in a range from ?5:95 to ?75:25. The dispersion can be used as a printing ink for producing electrically conductive films. The invention further provides an electrically conductive film comprising carbon nanotubes and graphene platelets, with the ratio by mass of carbon nanotubes to graphene platelets being situated within a range from ?5:95 to ?75:25.
    Type: Grant
    Filed: August 20, 2012
    Date of Patent: January 16, 2018
    Assignee: FUTURECARBON GMBH
    Inventors: Daniel Rudhardt, Thomas Buesgen, Stefanie Eiden, Diana Dimowa Landen, Gesa Behnken
