Patent number: 8470946Abstract: 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.Type: GrantFiled: August 20, 2012Date of Patent: June 25, 2013Assignee: The Regents of the University of CaliforniaInventor: Lawrence E.

Patent number: 8455865Abstract: Compositions are provided comprising aqueous dispersions of electrically conducting organic polymers and a plurality of nanoparticles. Films cast from invention compositions are useful as buffer layers in electroluminescent devices, such as organic light emitting diodes (OLEDs) and electrodes for thin film field effect transistors. Buffer layers containing nanoparticles have a much lower conductivity than buffer layers without nanoparticles. In addition, when incorporated into an electroluminescent (EL) device, buffer layers according to the invention contribute to higher stress life of the EL device.Type: GrantFiled: March 10, 2011Date of Patent: June 4, 2013Assignee: E I du Pont de Nemours and CompanyInventor: Che-Hsiung Hsu

Patent number: 8445025Abstract: Disclosed are the nanoparticle and the method for the same, and the preparing method includes steps of mixing polyethylenimine (PEI) with the poly(acrylic acid)-bound iron oxide (PAAIO) to form a PEI-PAAIO polyelectrolyte complex (PEC) and mixing the PEI-PAAIO PEC with genetic material such as plasmid DNA to form the PEI-PAAIO/pDNA magnetic nanoparticle. The PEI-PAAIO/pDNA magnetoplex is highly water dispersible and suitable for long term storage, shows superparamagnetism, low cytotoxicity, high stability and nice transfection efficiency, and thus the PEI-PAAIO PEC can replace PEI as a non-viral gene vector.Type: GrantFiled: March 29, 2011Date of Patent: May 21, 2013Assignee: Kaohsiung Medical UniversityInventors: Li-Fang Wang, Shuo-Li Sun, Yu-Lun Lo

Patent number: 8424200Abstract: An electromagnetic interference (EMI) shielding material includes a matrix of a dielectric or partially conducting polymer, such as foamed polystyrene, with carbon nanotubes or other nanostructures dispersed therein in sufficient concentration to make the material electrically conducting. The composite is formed by dispersing the nanotube material in a solvent in which the dielectric or partially conducting polymer is soluble and mixing the resulting suspension with the dielectric or partially conducting polymer. A foaming agent can be added to produce a lightweight foamed material. An organometallic compound can be added to enhance the conductivity further by decomposition into a metal phase.Type: GrantFiled: December 19, 2006Date of Patent: April 23, 2013Assignee: University of Virginia Patent FoundationInventors: Mool C.
