Patents by Inventor Christos Chochos

Christos Chochos has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Acid-doped polyelectrolyte modified carbon nanotubes and their use in high temperature PEM fuel cell electrodes
    Patent number: 8247521
    Abstract: New multifunctional aromatic copolymers bearing pyridine or pyrimidine units either in the main chain or side chain and single wall carbon nanotubes or multi wall carbon nanotubes as side chain pendants have been prepared. These multifunctional materials will combine both high proton and electrical conductivity due to the existence of polar pyridine or pyrimidine groups and carbon nanotubes within the same chemical structure. The prepared multifunctional materials can be used in the catalyst ink of the electrodes in high temperature PEM fuel cells.
    Type: Grant
    Filed: June 25, 2008
    Date of Patent: August 21, 2012
    Assignee: Advent Technologies
    Inventors: Christos Chochos, Nora Gourdoupi, Nikolas Triantafyllopoulos, Joannis Kallitsis
  • Multifunctional materials consisting of regioregular poly(3-alkylthiophene)s covalently attached on carbon nanotubes for photovoltaic applications
