| 20090053120 | CATALYST-SPREADING DEVICE IN A DEVICE FOR PRODUCING CARBON NANOTUBES - According to an exemplary embodiment of the present invention there is provided a catalyst-spreading device comprising: a mesh boat which stores catalyst to be spread on a substrate and includes a bottom having a mesh net, a transportation unit which transports the mesh boat or the substrate, and a vibration unit which vibrates the mesh boat to spread the catalyst on the substrate. | 02-26-2009 |
| 20100278713 | Method of manufacturing a carbon nanotube, and apparatus and system for performing the method - In a method of manufacturing a carbon nanotube, a boat configured to receive substrates is positioned outside of a synthesis space where the carbon nanotube is synthesized. The substrates are loaded into the boat. The boat is then transferred to the synthesis space. A process for forming the carbon nanotube is performed on the substrates in the synthesis space to form the carbon nanotube. Thus, the carbon nanotube may be effectively manufactured. | 11-04-2010 |
| 20100284897 | Apparatus and method for synthesizing carbon nanotube - An apparatus for synthesizing a carbon nanotube includes a reaction chamber, a cassette, a transferring member, a heater, a gas supply member and a gas exhausting part. The carbon nanotube is synthesized in the reaction chamber. The reaction chamber has a substantially vertical major axis. The cassette holds a plurality of substrates. The transferring member transfers the cassette along a direction substantially in parallel relative to the major axis to load/unload the cassette into/from the reaction chamber. The heater heats the reaction chamber. The gas supply member provides the reaction chamber with a gas for synthesizing the carbon nanotube. The gas exhausting member exhausts a remaining gas from the reaction chamber. Collecting the carbon nanotube may be facilitated and managing the reaction chamber may be effective to enhance a productivity of the carbon nanotube. | 11-11-2010 |

| 20080305031 | System and Method For Producing Carbon Nanotubes - A system for producing carbon nanotubes includes a reaction chamber in which a process is performed for producing a carbon nanotube on a synthetic substrate; a station part disposed at one side of the reaction chamber and provided with a first transporter for loading/unloading the synthetic substrate to/from the reaction chamber; a first transporter installed inside the station part for loading/unloading synthetic substrates to/from the reaction chamber; a substrate accommodating part in which a substrate to be loaded to the reaction chamber is accommodated or a synthetic substrate unloaded from the reaction chamber waits; a retrieve part for drawing out a synthetic substrate from the substrate accommodating part to retrieve a carbon nanotube produced on the synthetic substrate; a catalyst coating unit configured for coating a synthetic substrate with a catalyst before the synthetic substrate is accommodated in the substrate accommodating part of the station part; and a second transporter for transporting a synthetic substrate between the retrieve part and the substrate accommodating part and between the catalyst coating unit and the substrate accommodating part. | 12-11-2008 |
| 20090087371 | Apparatus for manufacturing carbon nanotubes and method of manufacturing carbon nanotubes with the same - Provided are an apparatus for manufacturing carbon nanotubes and a method of manufacturing carbon nanotubes with the apparatus. A plurality of carbon-nanotube-synthesizing units are disposed in series to continuously perform a carbon-nanotube-synthesizing process. Thus, carbon nanotubes having a uniform quality can be synthesized. | 04-02-2009 |
| 20090169465 | Fluidizing bed apparatus for producing carbon nanotubes and carbon nanotube production facility and method using the same - Provided is an apparatus for producing carbon nanotubes. The apparatus includes a reaction chamber and a rotating member. The reaction chamber provides a reaction space in which metal catalysts and a source gas react with one another to produce carbon nanotubes. The rotating member increases fluidizing of the metal catalysts in the reaction space to increase productivity and raise the gas conversion rate, thereby reducing the price of carbon nanotubes and preventing adhering of metal catalysts to the sidewall of the reaction chamber. | 07-02-2009 |
| 20100123274 | METHOD FOR SYNTHESIZING CONDUCTIVE COMPOSITE - Provided are an apparatus and method for synthesizing a conductive composite with enhanced electrical conductivity. The apparatus includes: an injection-molding machine which injection-molds pellets created by mixing carbon nanotubes (CNTs) with polymers; and an electric field generator which applies an electric field to the pellets that are melted while the melted pellets are injection-molded and thus rearranges the CNTs included in a composite into which the melted pellets are injection-molded. | 05-20-2010 |
