  • 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

  • Electro-switchable polymer film assembly and use thereof
    Patent number: 9231186
    Abstract: The invention relates to an electro-switchable polymer film assembly having a first and a second surface side, comprising at least one pair of electrodes (3, 4) and a polymer matrix (2), wherein structuring particles (5) can be embedded in the polymer matrix and the polymer matrix or the structuring particles consist of an electro-active polymer, wherein furthermore, the first and/or the second surface sides can be transferred from a plane condition into a structured condition by electric switching of the electro-active polymer.
