Multi Walled Carbon Nanotubes
Introduction:
Multi-walled carbon nanotubes (MWCNTs) consist of multiple layers of graphene arranged concentrically to form cylindrical nanostructures. Each layer comprises a single-atom-thick sheet of carbon atoms arranged in a hexagonal lattice.
The diameters of MWCNTs typically range from about 2 to 100 nanometers, with each additional layer contributing to the diameter.
These nanotubes display unique properties, including high strength, exceptional electrical and thermal conductivity, and a large surface area-to-volume ratio.
