    Abstract: Metamaterials or artificial negative index materials (NIMs) have generated great attention due to their unique and exotic electromagnetic properties. One exemplary negative dielectric constant material, which is an essential key for creating the NIMs, was developed by doping ions into a polymer, a protonated poly (benzimidazole) (FBI). The doped PBI showed a negative dielectric constant at megahertz (MHz) frequencies due to its reduced plasma frequency and an induction effect. The magnitude of the negative dielectric constant and the resonance frequency were tunable by doping concentration. The highly doped PBI showed larger absolute magnitude of negative dielectric constant at just above its resonance frequency than the less doped PBI.

  • Patent number: 8309662
    Abstract: A process for producing a solution blend of a polybenzimidazole (PBI) and a polyetherketoneketone (PEKK). The PBI is mixed with sulfuric acid at a temperature between 40° C. and 80° C. for 30 minutes to 2 hours to produce a PBI solution then cooled to room temperature to form a cooled PBI solution. Then PEKK is added to the cooled PBI solution to form a mixture and that mixture is stirred from 30 minutes to 2 hours at room temperature to form a stirred mixture. The stirred mixture is poured into an excess of water being stirred swiftly to form an aqueous mixture. The aqueous mixture is filtered to produce a blend. The blend is washed with water and dried. The resulting blend can yield a blend in all proportion from 1/99 PBI/PEKK to 99/1 PBI/PEKK.

  • Patent number: 8298450
    Abstract: A polybenzimidazole-base complex includes a polybenzimidazole-based material and a base, wherein a peak corresponding to NH of an imidazole ring of the polybenzimidazole-based material does not appear at a chemical shift of 12 to 15 ppm in a 1H nuclear magnetic resonance (1H-NMR) spectrum of the polybenzimidazole-base complex. A crosslinked material may be formed as a polymerization product of a polybenzimidazole-base complex and a benzoxazine-based monomer. The crosslinked material may be used an electrolyte membrane for a fuel cell comprising the crosslinked material, and a fuel cell may include the electrolyte membrane.

  • Patent number: 8263732
    Abstract: [Object] To obtain an alignment film having excellent alignment stability of a liquid crystal and a high voltage holding ratio by application of linearly polarized light to a polyamic acid having a specific structure and then imidization under heat. [Solving Means] A photo-alignment film is obtained by: applying a polyamic acid solution on a substrate, where the polyamic acid contains, in its main chain, at least a group having unsaturated groups having 1 to 3 carbon-carbon double bonds or 1 to 4 triple bonds; vaporizing a solvent from a film formed; applying linearly polarized light to the film after the vaporization of the solvent; and then heating the film to imidize the polyamic acid.

    Abstract: Crosslinked polybenzoxazines obtained by crosslinking a monofunctional first benzoxazine monomer and a multifunctional second benzoxazine monomer with a crosslinkable compound, an electrolyte membrane including the same, a method of preparing the electrolyte membrane, a fuel cell including the electrolyte membrane having the crosslinked polybenzoxazines using the method. The crosslinked polybenzoxazines have strong acid trapping capability, improved mechanical properties, and excellent chemical stability as it does not melt in polyphosphoric acid. Even as the amount of impregnated proton carrier and the temperature are increased, mechanical and chemical stability is highly maintained, and thus the electrolyte membrane can be effectively used for fuel cells at a high temperature.
