| 20080206448 | Low Work Function Material - The present invention is directed toward methods for incorporating low work function metals and salts of such metals into carbon nanotubes for use as field emitting materials. The present invention is also directed toward field emission devices, and associated components, comprising treated carbon nanotubes that have, incorporated into them, low work function metals and/or metal salts, and methods for making same. The treatments of the carbon nanotubes with the low work function metals and/or metal salts serve to improve their field emission properties relative to untreated carbon nanotubes when employed as a cathode material in field emission devices. | 08-28-2008 |
| 20080206559 | LUBRICANT ENHANCED NANOCOMPOSITES - Strings configured for use in sports racquets and musical instruments are fabricated as a plastic core wrapped with one or more filaments of plastic. The strings are coated with a material composite that includes rigid nanoparticles, and lubricated nylon. The rigid nanoparticles may include clay or carbon nanotubes. The strings are coated with the material composite using various processes that result in a coating thickness of between 0.1 and 200 μm. The material composite may further include impact modifiers. The strings experience extended life due to reduced frictional wear and improved mechanical properties. | 08-28-2008 |
| 20080300357 | Carbon Nanotube-Reinforced Nanocomposites - A combination of MWNTs (herein, MWNTs have more than 2 walls) and DWNTs significantly improves the mechanical properties of polymer nanocomposites. A small amount of DWNTs reinforcement (<1 wt. %) significantly improves the flexural strength of epoxy matrix nanocomposites. A same or similar amount of MWNTs reinforcement significantly improves the flexural modulus (stiffness) of epoxy matrix nanocomposites. Both flexural strength and flexural modulus of the MWNTs and DWNTs-coreinforced epoxy nanocomposites are further improved compared with same amount of either DWNTs or MWNTs-reinforced epoxy nanocomposites. In this epoxy/DWNTs/MWNTs nanocomposite system, SWNTs may also work instead of DWNTs. Besides epoxy, other thermoset polymers may also work. | 12-04-2008 |
| 20090035570 | CARBON NANOTUBE-REINFORCED NANOCOMPOSITES - Carbon nanotubes (CNTs) are so long that they cannot be penetrated inbetween carbon fibers during a prepreg preparation process, and are shortened in order for them not to be filtered out by the carbon fibers. This results in a huge improvement of the mechanical properties (flexural strength and flexural modulus) compared with neat epoxy. | 02-05-2009 |
| 20090095704 | PATTERNING CNT EMITTERS - An industrial scale method for patterning nanoparticle emitters for use as cathodes in a display device is disclosed. The low temperature method can be practiced in high volume applications, with good uniformity of the resulting display device. The method steps involve deposition of CNT emitter material over an entire surface of a prefabricated composite structure, and subsequent removal of the CNT emitter material from unwanted portions of the surface using physical methods. | 04-16-2009 |
| 20100285212 | COMPOSITES - Improved mechanical properties of either clay or carbon nanotube (CNT)-reinforced polymer matrix nanocomposites are obtained by pre-treating nanoparticles and polymer pellets prior to a melt compounding process. The clay or CNTs are coated onto the surfaces of the polymer pellets by a milling process. The introduction of moisture into the mixture of the nanoparticles and the polymer pellets results in the nanoparticles more easily, firmly, and thoroughly coating onto the surfaces of the polymer pellets. | 11-11-2010 |
| 20110027603 | Enhancing Thermal Properties of Carbon Aluminum Composites - An article of manufacture comprises a carbon-containing matrix. The carbon-containing matrix may comprise at least one type of carbon material selected from the group comprising graphite crystalline carbon materials, carbon powder, and artificial graphite powder. In addition, the carbon-containing matrix comprises a plurality of pores. The article of manufacture also comprises a metal component comprising Al, alloys of Al, or combinations thereof. The metal component is disposed in at least a portion of the plurality of pores. Further, the article of manufacture comprises an additive comprising at least Si. At least a portion of the additive is disposed in an interface between the metal component within the pores and the carbon-containing matrix. The additive enhances phonon coupling and propagation at the interface. | 02-03-2011 |
| 20110160346 | DISPERSION OF CARBON NANOTUBES BY MICROFLUIDIC PROCESS - Improved mechanical properties of carbon nanotube (CNT)-reinforced polymer matrix nanocomposites are obtained by functionalizing the CNTs with a compound that bonds well to an epoxy matrix before dispersing the solution using a microfluidic process. Well-dispersed particles are obtained that sufficiently improve mechanical properties of the nanocomposites, such as flexural strength and modulus. The resulting composite material is used for coatings on marine vessels. | 06-30-2011 |
