What are Single-Walled Carbon Nanotubes?

Single-walled carbon nanotubes (SWNTs) are one-dimensional nanomaterials. SWNTs can be considered as sheets of graphene that have been seamlessly rolled up to form a long hollow tube, with wall thickness of a single atom. Depending on the orientation of the graphene lattice with respect to the tube axis they are twisted, three typical types of CNTs, armchair, zigzag, and chiral can be obtained. Single-walled carbon nanotubes with different electrical and physical properties can be achieved by rolling a single graphene sheet in different directions.

Short Single-Walled Carbon Nanotubes Thermal Properties

Thermal Properties

Exceptional Thermal Properties

Both theory and experiments have demonstrated that the nanotube electronic bandgap increases as their length shortens, especially down to tens of nanometres when quantum confinement effect plays an important role along the length axis. Shortening nanotubes is also an efficient approach for improving gas or ion storage capabilities of carbon nanotube-based materials.

Short single walled carbon nanotubes (sSWCNTs) possess exceptional thermal, mechanical, and electrical properties. They find applications in diverse fields including energy storage, drug discovery, bio-sensing, catalysts, composites, molecular electronics, solar cells and nanomechanical devices.
