What are Carbon Nanotubes?

Carbon nanotubes are nanometer-scale tubes made entirely of carbon atoms. They have unique structural features, including:

  1. Single-Walled Carbon Nanotubes (SWCNTs): Consist of a single cylindrical layer of graphene wrapped around itself to form a tube.
  2. Multi-Walled Carbon Nanotubes (MWCNTs): Consist of several concentric graphene tubes stacked inside each other, resembling a "tube within a tube" structure.

Carbon nanotubes exhibit exceptional properties, such as high tensile strength, lightweight, excellent electrical and thermal conductivity, and high surface area. These qualities make CNTs ideal for use in various applications, including composites, energy storage, sensors, and electronic devices.
