What are Carbon Nanotubes?
Carbon nanotubes (CNTs) are cylindrical molecules consisting of rolled-up sheets of single-layer carbon atoms (graphene). They exhibit extraordinary strength, unique electrical properties, and are efficient conductors of heat. Their structure can be single-walled (SWCNT) or multi-walled (MWCNT).
History and Discovery
Carbon nanotubes were first observed by
Sumio Iijima in 1991. This discovery opened the door to extensive research and development, leading to potential applications in various fields such as electronics, materials science, and medicine.
