With state-of-the-art single-wall carbon nanotube manufacturing and processing
equipment as a backdrop, Norman-based SouthWest
NanoTechnologies Inc. (SWeNT) welcomed nearly 200 guests to celebrate the
dedication of the company's new 18,000-square-foot, $3.9 million facility Thursday
Oklahoma Lt. Gov. Jari Askins, Secretary of Commerce and Tourism Natalie Shirley,
Norman Mayor Cindy Rosenthal and Norman Economic Development Coalition executive
director Don Wood joined SWeNT chairman W. Arthur “Skip” Porter,
CEO David Arthur and founder and chief scientist Daniel Resasco in the program.
"Our mission is to make single-wall nanotubes a commercial reality, and
we have overcome all of the barriers that previously prevented that: inconsistent
quality, inability to scale up and high production costs,” Arthur said.
“Since moving into the plant in June, we have increased production capacity
for high-quality single-wall carbon nanotubes by 100-fold at one-tenth the cost.
“This dramatic expansion in capacity enables us to meet the demand we
expect from our customers for consistently high-quality single-wall carbon nanotubes
at competitive prices,” he added.
Single-wall carbon nanotubes consist of a hollow cylinder of carbon with a
diameter equal to approximately one nanometer – a billionth of a meter.
Due to their unusual structure, they exhibit extraordinary optical and electronic
properties, tremendous strength and flexibility, and high thermal and chemical
stability. These remarkable properties make them suitable for a wide range of
applications in the automotive, aeronautics, electronics, displays, energy and
SWeNT produces single-wall carbon nanotubes using the scalable, cost-efficient
CoMoCAT® catalytic process developed by a University of Oklahoma research
team led by Resasco, who holds the Douglas and Hilda Bourne Chair of Chemical
Engineering and George Lynn Cross Research Professorship at OU. The CoMoCAT®
process ensures consistent high quality and the flexibility to provide tailored
Potential applications for single-wall carbon nanotubes include:
- Reinforced polymer composites used for thin-film membranes on antennas,
second surface mirrors and thermal optical coatings on aircraft and spacecraft
- Bulletproof body and vehicle armor, due to single-wall carbon nanotubes’
ability to be spun into fibers that are 20 times tougher than steel and 17
times stronger than Kevlar®
- Reinforced ceramics or polymer composites to replace materials from which
wind turbine blades are currently made, which will enable the blades to be
longer yet lighter, and therefore more efficient
- Conductive film coatings, which provide an inexpensive, long-lasting material
for touch screens in such devices as automatic teller machines, tablet personal
computers and ticketing terminals
- Transparent conducting current collectors in organic solar cells, a promising
low-cost, flexible alternative to solar cells made with silicone
- Replacement for much of the expensive platinum currently required in fuel
- Faster, denser semiconducting chips and “nanowires” to interconnect
- Field emission displays, in which nanotubes combine the high-quality video
of cathode ray tubes with the flatness of LCD and plasma displays but without
the burn-in and poor viewing angles associated with today's flat-panel versions
- Inks for use in electronic readers, animated posters and active clothing
- Noninvasive cancer treatment delivery systems, taking drugs directly to
the source of disease, and thereby reducing the toxicity of chemotherapy agents
and other drugs to healthy cells
- Combined with natural antibacterial proteins, helping to combat the spread
of infections through contact with contaminated surfaces.
In July, SWeNT announced that the National Institute of Standards and Technology
(NIST) will use SWeNT® SG65 single-wall carbon nanotubes as the starting
material for a Standard Reference Material. SRMs are used to perform instrument
calibrations, verify the accuracy of specific measurements and support the development
of new measurement methods. Industry, academia and government use NIST SRMs
to facilitate commerce and trade and to advance research and development.
In addition to the Oklahoma facility, SWeNT maintains an applications and business
development center in the Route 128/Boston, Massachusetts area to help customers
integrate SWeNT nanotubes into their applications.
