Title:
DOUBLE-WALLED CARBON NANOTUBE, ALIGNED DOUBLE-WALLED CARBON NANOTUBE BULK STRUCTURE, AND PROCESS FOR PRODUCTION OF THE CARBON NANOTUBE OR THE BULK STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2007/061143
Kind Code:
A1
Abstract:
Disclosed is an aligned double-walled carbon nanotube bulk structure which
comprises multiple aligned double-walled carbon nanotubes and has a height
of 0.1 μm or more. In the bulk structure, the double-walled carbon nanotubes
can be produced by chemical vapor deposition (CVD) in the presence of a metal catalyst
having a controlled particle size and a controlled thickness, preferably in
the presence of water. It becomes possible to provide a double-walled carbon
nanotube which is free from the catalyst contamination, has a high purity, is
easy to control the alignment or growth, can be formed through the formation of
a bulk structure, and has an excellent electron-emitting property (particularly,
a bulk structure of aligned, double-walled carbon nanotubes) and also provide
a technique for production of the carbon nanotube.
