Carbon nanotubes offer an array of superior
properties such as high strength, high stiffness, non-corrosiveness, low
density, and high electrical and thermal conductivities. Carbon nanotube
composites are considered the next generation of ultra-strong and
multifunctional materials for many applications.
Aligning and packing carbon nanotubes (CNTs) is
challenging due to their nanoscale size.
CNTs are very difficult to process as they become highly entangled
during synthesis and post-purification treatments. Current manufacturing techniques are not
capable of controlling hierarchical organizations, and are unable to produce
aligned, densely packed, and pure CNT sheets/fibers and composites. While there has been immense progress towards
improving CNTs over the last decade, there is still much development needed to
improve manufacturability and achieve high quality carbon nanotube composites.
A researcher from the University of New Mexico has
developed an innovative process to create continuous, high quality carbon
nanotube (CNT) fibers, unidirectional sheets, and polymer composites. Manufacturing is scalable and presents an
unprecedented form of inexpensive technology to produce polymer-carbon nanotube
composites. This method does not require any sophisticated equipment or high
energy dispersive methods, it is highly scalable, and achieves highly-aligned carbon
nanotube fibers that are >99% pure. This method is expected to achieve polymer composites with
tensile strength above 10 GPa, stiffness higher than 400 GPa, elongation in
excess of 8%, toughness higher than 300 J/g, electrical conductivity of at
least 10^6 S.m^-1 and thermal conductivity larger than 500
STC has filed intellectual property on this exciting new technology and
