4. What are the Carbon Nanotubes
Carbon nanotubes (CNTs) are allotropes of carbon
with cylindrical nanostructure.
Constructed with length-to-diameter ratio of up to
132,000,000:1 .
Carbon nanotube is a tube shaped material made of
carbon , having a diameter measuring on the
nanometer.

5. History of Carbon Nanotubes
The initial history of nanotubes started in the 1970s. A preparation of the planned carbon filaments was
completed by Morinobu Endo who was earning his Ph.D. at the University of Orleans, France.
In 1991 the true first invention of nanotube was finally made. In 1993 Iijima and Donald Bethune
found single walled nanotubes known as buckytubes.
Roger Bacon is technically the first scientist to discover these hollow tubes of carbon that are changing
lives on a daily basis

6. Types of carbon Nanotubes
Classified mainly in two types
Single Walled Nanotubes
Multi Walled Nanotubes
Related structures
