Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene). They were discovered in 1991 by Sumio Iijima, although similar structures had been identified earlier. These nanotubes are known for their extraordinary strength and electrical properties. They are among the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively. This unique combination of properties makes CNTs a potentially critical material in both materials science and nanotechnology.
