| 20090124705 | CARBON NANOTUBE POWDER, CARBON NANOTUBES, AND PROCESSES FOR THEIR PRODUCTION - A novel carbon nanotube powder containing carbon nanotubes which have a roll-like structure, also novel carbon nanotubes having a roll-like structure, novel processes for the production of the carbon nanotube powders and of the carbon nanotubes, and their use as an additive or substrate for various applications are described. | 05-14-2009 |
| 20120149824 | CARBON NANOTUBE AGGLOMERATE - The invention relates to a method for producing carbon nanotubes in the agglomerated form and thus obtained novel carbon nanotube agglomerates. | 06-14-2012 |
| 20120234204 | VAPOR PHASE FUNCTIONALIZATION OF CARBON NANOTUBES - The present invention provides a process for the production of functionalized carbon nanotubes. The inventive process for the production of functionalized carbon nanotubes involves reacting carboxylic acid moieties of oxidized carbon nanotubes with vapors of a compound containing carboxylic acid reactive groups to produce functionalized carbon nanotubes. The present invention also provides a composition made from a plastic resin and functionalized carbon nanotubes produced by reacting carboxylic acid moieties of oxidized carbon nanotubes with a vapor containing carboxylic acid reactive groups to produce functionalized carbon nanotubes. The inventive process is useful with single-walled carbon nanotubes, double-walled carbon nanotubes and multi-walled carbon nanotubes. | 09-20-2012 |
| 20130039839 | PRODUCTION OF CARBON NANOTUBES - The invention relates to a novel process for the production of catalysts for the production of carbon nanotubes in agglomerated form, which are characterised by a low bulk density. This invention likewise provides the catalysts, their use in the production of carbon nanotubes in high catalyst-specific yields, and the carbon nanotubes produced by this process. | 02-14-2013 |
| 20130203928 | PROCESS FOR PRODUCING POLYMER-CNT COMPOSITES - A process for producing polymer-carbon nanotube (CNT) composites comprises the steps of: (A) providing carbon nanotube agglomerates with an average agglomerate size of ≧0.02 mm to ≦6 mm; (B) contacting the carbon nanotube agglomerates with an impregnation material, the contacting being performed in such a way that ≧50 wt. %, based on the weight of the carbon nanotubes, of the carbon nanotube agglomerates after contacting still has an average agglomerate size of ≧0.02 mm; and (C) incorporating the carbon nanotube agglomerates which have been contacted with an impregnation material and obtained in step (B) into a thermoplastic polymer material or into a reactive resin system. The invention further relates to carbon nanotube agglomerates which have been contacted with an impregnation material and to a polymer composite comprising carbon nanotubes. | 08-08-2013 |
