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.

Acid-doped polyelectrolyte modified carbon nanotubes and their use in high temperature PEM fuel cell electrodes

Facile ways towards the integration of the regioregular poly(3-alkylthiophene)s onto carbon nanotubes, providing multifunctional materials that combine the extraordinary properties of the carbon nanotubes with those of regioregular poly(3-alkylthiophene)s, are presented.

Multifunctional materials consisting of regioregular poly(3-alkylthiophene)s covalently attached on carbon nanotubes for photovoltaic applications

High temperature polymer electrolyte membranes bearing pyridine and tetramethyl biphenyl moieties are provided. Preferred polymers can exhibit good mechanical properties, high thermal and oxidative stability and high doping ability with strong acids. Further provided are MEA on PEMFC type single cells.

Aromatic polyether copolymers and polymer blends and fuel cells comprising same

The subject invention relates to the development and characterization of a new series of poly (arylene ether) copolymers containing pyridine and biphenyl or hydroquinone moieties. Preferred polymers can exhibit very good mechanical properties, high thermal and oxidative stability and high doping ability with strong acids. The invention further relates to the preparation and application of MEA on PEMFC type single cells.
