20080224101 | POLYVINYLIDENE FLUORIDE COMPOSITES AND METHODS FOR PREPARING SAME - An electrically conductive composite comprising a polyvinylidene fluoride polymer or copolymer and carbon nanotubes is provided. Preferably, carbon nanotubes may be present in the range of about 0.5-20% by weight of the composite. | 09-18-2008 |
20090093360 | METHOD FOR PREPARING CATALYST SUPPORTS AND SUPPORTED CATALYSTS FROM SINGLE WALLED CARBON NANOTUBES - A new method for preparing a supported catalyst is herein provided. A carbon nanotube structure such as a rigid porous structure is formed from single walled carbon nanotubes. A metal catalyst is then loaded or deposited onto the carbon nanotube structure. The loaded carbon nanotube is preferably ground to powder form. | 04-09-2009 |
20090208391 | PROCESSES FOR THE RECOVERY OF CATALYTIC METAL AND CARBON NANOTUBES - A new method for recovering a catalytic metal and carbon nanotubes from a supported catalyst is provided. The carbon nanotube, including carbon nanotube structures, may serve as the support for the catalytic metal. The valence state of the catalytic metal, if not already in the positive state, is raised to a positive state by contacting the supported catalyst with a mild oxidizing agent under conditions which does not destroy the carbon nanotube. The supported catalyst is simultaneously or subsequently contacted with an acid solution to dissolve the catalytic metal without dissolving the carbon nanotube. | 08-20-2009 |
20100086471 | Mixed structures of single walled and multi walled carbon nanotubes - The invention relates to carbon nanotube structures containing both single walled and multi walled carbon nanotubes, and methods for preparing same.
