Properties of Single Walled Carbon Nanotubes (SWCNTs)

Mechanical Strength

Single-walled carbon nanotubes have extremely high strength, and Young’s modulus can reach 1TPa. As a reinforcing material, they have the inherent properties of carbon fiber, the electrical and thermal conductivity of metal materials, the heat resistance and corrosion resistance of ceramic materials, the softness and weavability of textile fibers, and the light processability of polymer materials.

Thermal Performance

Single-walled carbon nanotubes have extremely high thermal conductivity. The theoretical value can reach 6000W/mK at room temperature. There are large differences in the macroscopic thermal conductivity of carbon nanotubes prepared by different methods. However, the theoretical thermal conductivity of carbon nanotubes is much higher than that of other previously known materials.

Electrical Properties

In terms of electrical properties, single-walled carbon nanotubes have excellent conductivity. With only a very small amount of addition, they can form a three-dimensional conductive network when embedded in a material matrix. This has little effect on the material’s original color and other main properties.

Composite Enhancement

SWCNTs have one of the highest tensile strengths and elastic moduli of any material (50 GPa and 1000 GPa, respectively). They are suitable for strengthening various materials, including polymer composites. In polymer composites, the ideal dispersion of isotropically distributed SWCNTs was achieved. For every 1% (by weight) of SWCNTs added, the tensile strength increased by 100 MPa.

Single-walled Carbon Nanotubes FAQs

They are cylindrical nanostructures made of a single layer of carbon atoms arranged in a hexagonal lattice. They are a unique allotrope of carbon with exceptional mechanical, electrical, and thermal properties.

SWCNTs comprise a single carbon layer, while MWCNTs comprise multiple concentric graphene layers. SWCNTs have unique electronic properties, whereas MWCNTs are often stronger and more robust.

  • High electrical conductivity
  • Excellent thermal conductivity
  • Exceptional strength-to-weight ratio
  • Flexible and lightweight
  • High surface area

The diameter of SWCNTs typically ranges from 0.7 to 2 nanometers. Their length can vary from a few micrometers to several millimeters.

Yes, SWCNTs can be chemically modified to improve compatibility with other materials, making them suitable for a broader range of applications. These include targeted drug delivery and enhanced composite materials.

Advances in scalable production and functionalization methods are expected to broaden the adoption of SWCNTs in fields such as electronics, renewable energy, and medicine.
