ARNHEM, the Netherlands, January 11, 2013 /PRNewswire/ --

Groundbreaking scientific research has been published on carbon nanotube fiber
                with high thermal and electrical conductivity.

Researchers at Teijin Aramid, based in  the  Netherlands, and Rice
University in  the  USA today published their research findings on a new
generation of super fibers in the leading scientific journal, Science. For the
first time in history, it has been possible to spin carbon nanotubes (CNTs)
into a super fiber that has very high thermal and electrical conductivity and
good textile performance. Carbon nanotubes, the building blocks of the fiber,
which is as thin as a strand of DNA, combine the best properties of thermal
and electrical conductivity, strength, modulus and flexibility.

For several years, leading researchers at Rice University, including Nobel
prize winner Richard Smalley (Chemistry, 1996), along with researchers at
Teijin Aramid, have been working on producing carbon nanotubes and forming
them into useful macroscopic objects with extraordinary, new performance
properties. To spin a high-performance carbon nanotube textile thread (fiber),
the nanotubes must be perfectly stacked and orientated along the fiber axis.
The most efficient method to produce this high performance fiber is to
dissolve CNTs in a super acid, followed by wet-spinning. This is a patented
process which has been used since the 1970s in spinning Teijin Aramid's Twaron
super fiber.

"Our carbon nanotube fibers combine high thermal and electrical conductivity,
like that seen in metals, with the flexibility, robust handling and strength
of textile fibers", explained Marcin Otto, Business Development Manager at
Teijin Aramid. "With that novel combination of properties it is possible to
use CNT fibers in many applications in the aerospace, automotive, medical and
(smart) clothing industries."

Teijin's cooperation and involvement was crucial to the project. Twaron
technology enabled improved performance, and an industrially scalable
production method. That makes it possible to find applications for CNT fibers
in a range of commercial or industrial products. "This research and ongoing
tests offer us a glimpse into the potential future possibilities of this new
fiber. For example, we have been very excited by the interest of innovative
medical doctors and scientists exploring the possibilities to use CNT fiber in
surgical operations and other applications in the medical field", says Marcin
Otto. Teijin Aramid expects to replace the copper in data cables and light
power cables used in the aerospace and automotive industries, to make aircraft
and high end cars lighter and more robust at the same time. Other applications
could include integrating light weight electronic components, such as
antennas, into composites, or replacing cooling systems in electronics where
the high thermal conductivity of carbon nanotube fiber can help to dissipate
heat.

Teijin Aramid is currently trialing samples of CNT fiber on a small scale with
the most active prospective customers. Building up a robust supply chain is
high on the project team's list of priorities. As well as their carbon fiber,
aramid fiber and polyethylene fiber, this new carbon nanotube fiber is
expected to allow Teijin to offer customers an even broader portfolio of super
fibers.

Teijin Aramid is running this project in collaboration with research groups
led by Professor Matteo Pasquali and Professor Jun Kono at Rice University
(Houston, USA) and allied research centers at Technion-Israel Institute of
Technology (Haifa, Israel) and the US Air Force Research Laboratory (Dayton,
USA). This ideal combination of effective experimental skills, knowledge and
expertise makes this a winning team. The research was funded by Teijin Aramid
BV and its parent company, Teijin Limited.
