What is a carbon nanotube?
Q: What is a carbon nanotube?
A: A carbon nanotube is an allotrope of carbon that is shaped like a tube of carbon atoms.
Q: How durable and strong are carbon nanotubes?
A: Carbon nanotubes are very tough and hard to break, but still relatively light.
Q: What are some potential uses for carbon nanotubes?
A: Carbon nanotubes may one day be used for bulletproof armour and other uses needing hard, lightweight materials.
Q: Do carbon nanotubes conduct electricity?
A: Yes, a few carbon nanotubes also let electricity through them.
Q: How does the electrical conductivity of carbon nanotubes compare to metals like copper and silver?
A: Some carbon nanotubes may be up to 1,000 times better at conducting electricity than metals like copper and silver.
Q: Are all carbon nanotubes the same length?
A: No, some carbon nanotubes are very long.
Q: What makes carbon nanotubes particularly useful for certain applications?
A: The high strength and lightweight nature of carbon nanotubes make them particularly useful for certain applications.
