What Are Carbon Nanotubes (CNTs)?

Carbon nanotubes are allotropes of carbon with a cylindrical nanostructure, consisting of rolled-up sheets of single-layer carbon atoms (graphene). There are two main types:

Single-Walled Carbon Nanotubes (SWCNTs): One layer of graphene rolled into a cylinder. Known for high electrical conductivity and flexibility.
Multi-Walled Carbon Nanotubes (MWCNTs): Multiple layers of graphene. They offer superior mechanical strength and are more cost-effective for industrial uses.
