  • Patent number: 8883043
    Abstract: Poly(anilineboronic acid)/phosphate nanoparticle dispersions are produced in high yields using the reactivity of the boronic acid moiety with phosphate in the presence of fluoride. The poly(anilineboronic acid)/phosphate dispersions have been characterized using spectroscopic, microscopic and electrochemical techniques. According to 11B NMR studies, the formation of anionic tetrahedral boronate group in phosphoric acid in the presence of fluoride forms the basis of self-doped, stabilized PABA nanoparticle dispersion. Transmission electron microscope images show that 25-50 nm diameter PABA nanoparticles are formed under these conditions. UV-vis, FT-IR-ATR spectroscopic and cyclic voltammetric results confirm the formation of the conducting form of PABA.

  • Patent number: 8470946
    Abstract: Carbon nanotube (CNT) yarns and sheets having enhanced mechanical strength using infused and bonded nano-resins. A CNT yarn or sheet is surface-activated to produce open bonds in the CNT walls prior to resin infusion. The CNT yarn or sheet is infused with a low viscosity nano-resin that penetrates spaces between individual CNTs and is cured to cross-link and chemically bond to the CNT walls, either directly or through a functional molecule, to bond the individual CNTs or ropes to each other. The nano-resin can comprise dicyclopentadiene having an uncured viscosity near that of water. The cross-linking process involves ring-opening metathesis polymerization and catalysis of the nano-resin in combination with a functionalizing material such as norbornene, to enhance bonding between the carbon and nano-resin. The process increases load capability, tensile strength, and elastic modulus of the yarns and sheets, for use as a structural component in composite materials.

  • Publication number: 20120232458
    Abstract: Systems and methods utilize semipermeable nanotubes in conjunction with application of controlled electrical potentials across semipermeable nanotube walls allow selective transport of charged impurities (e.g., charged impurities, ions, etc.) from a fluid into these nanotubes. Impurities collected in these nanotubes can then be removed from the fluid, (e.g., blood) as a waste stream. A collection of semipermeable nanotubes each carrying a waste stream can be aggregated and merged into a ureter for excretion thereby providing an artificial kidney system. Sensors that detect/measure various impurities may be included in the system to feed information to a microprocessor to inform on concentrations of impurities, and thereby control electrical potentials applied to the system.

  • Publication number: 20120177934
    Abstract: The invention relates to a method for producing stretchable electrodes, where electrically conductive carbon particles, especially carbon nanotubes, are introduced into a coating comprising an elastomer. In said method, a preparation of non-aggregated carbon particles having an average particle diameter ranging from=0.3 nm to=3000 nm in a solvent acts upon a coating comprising an elastomer. The solvent can cause a coating comprising an elastomer to swell. The duration of the action is calculated so as to be insufficient to dissolve the elastomer. Optionally, another electrically conductive layer is applied. The invention also relates to a stretchable electrode obtained in said manner and to the use thereof.

  • Patent number: 8206678
    Abstract: The invention relates to a vapor grown carbon fiber having a mean fiber diameter of 80 to 500 nm, an aspect ratio of 100 to 200 and preferably a bulk density of 0.02 g/cm3 or less, wherein filaments having a diameter within ±20% of the mean fiber diameter occupies 65% (on a number basis) or more of the total. The production method involves thermal decomposition of a carbon source at 800 to 1,300° C. in the presence of, as a catalyst, a transition metal compound having a vapor pressure of 0.13 kPa (1 mmHg) or more at 150° C. and spraying of the carbon source and the transition metal compound in gas form toward the reactor inner wall to allow reaction to proceed. The vapor grown carbon fiber having a larger aspect ratio has excellent dispersibility, and when added in a resin, a smaller amount contributes to enhancement in electroconductivity and thermal conductivity, as compared with a case using conventional one.
