Background

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.

Technology Description

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 W/mK.

Advantages/Applications

  • Superior carbon nanotube composites
  • Low cost, scalable, sustainable and non-destructive processing of carbon nanotubes for manufacturing purposes
  • Water based wet-chemistry process within environmental, health and safety (EHS) guidelines
  • Manufacturing is quick and does not require sophisticated equipment or high energy dispersive methods
  • Unprecedented tailoring over the structural levels in aligned CNT architectures
  • Structural and industrial applications
