This composite is in the form of a network in which at least some of the carbon nanotubes connect two or more aggregates that are not directly contacting each other, creating an entangled structure in which a plurality of aggregates and a plurality of carbon nanotube strands are intertwined. Due to the highly conductive properties of the carbon nanotubes in this composite, charge carriers can be rapidly transferred between the self-assembled aggregates. This composite may be prepared by preparing a dispersion in which the nanoparticles and/or carbon nanotubes are dispersed without any organic binders, simultaneously spraying the nanoparticles and the carbon nanotubes on a current collector through electrospray, and then subjecting the composite material formed on the current collector to a heat treatment.

  • Patent number: 8153699
    Abstract: A surfacing composition made of recycled paint, which requires no priming, has a non-reflective “flat” appearance, and is partially composed of dried paint. The composition provides a useful application for used or excess household paint, which would otherwise require special methods of disposal and potentially create future toxic cleanup problems. The composition is made of granular dried paint and a water-based sealer, which can be spread on a surface to repair imperfections. The surface can then be finished, and no priming is required. Due to the composition's flat appearance, the patch does not display any characteristic sheen where the repair has been made. The composition provides a simple means of recycling paint, and provides a simple and inexpensive means of repairing imperfections in walls and other surfaces while saving the step of priming the patch before painting or repainting.

  • Publication number: 20120076927
    Abstract: A thermal treatment process for improving thermo-mechanical properties of ceramic matrix composite materials such as silicon carbide (SiC) matrix composites is described. The treatment process removes excess silicon and/or other process-related defects from the SiC-based matrix as well as the fiber interfacial coating. This invention can be practiced with minimal strength loss for as-fabricated composites formed from high-strength continuous-length ceramic and carbon-based fibers that are functionally stable to 1600° C. and above. The invention provides a method for significantly improving composite thermal conductivity and creep resistance, and for reducing composite porosity.
