U.S. Patent 7,646,588, FIG. 10 is a view showing a scanning electron microphotograph (30,000.times. magnification) of a section of Fuji Xerox carbon nanotube film for use in capacitors.
Fuji
Xerox Co., Ltd. (Tokyo, JP) scientists Tomoko Miyahara and Kazunori
Anazawa developed a nanofabrication process to produce carbon nanotube
films for use in capacitors. The carbon nanotube film has potential use in
electrical, electronic, mechanical, physical, chemical, biological and other
applications. A microwave absorber with a high wave absorption efficiency
and a resistance element having a high electric conductivity may also be produced
with the carbon nanotube film.

The
Fuji carbon nanotube film includes a first carbon nanotube group that is an
aggregate of carbon nanotubes crosslinked to each other to form a network
structure and a second carbon nanotube group that is an aggregate of carbon
nanotubes having a diameter different from a diameter of the carbon nanotubes
in the first carbon nanotube group, wherein the first carbon nanotube group and
the second carbon nanotube group are in admixture.

Carbon
nanotubes which are not in a hollow tube form such as carbon nanocoil
(generally spiral coil form), carbon nanobead (generally spiral coil type
carbon nanotube), carbon nanobead (carbon nanotube having a tube piercing a
spherical bead made of amorphous carbon, etc.), cup stack type carbon nanotube
and carbon nanotube covered by carbon nanohorn or amorphous carbon on the
periphery can also be used as carbon nanotube in the to form nano-carbon films.

Also
carbon nanotubes including materials encapsulated in them such as
metal-encapsulated carbon nanotube including a metal or the like encapsulated
within or peapod carbon nanotube having a fullerene or a metal-encapsulated
fullerene encapsulated in carbon nanotube can be used as carbon nanotube for
carbon nanotube films.
