What are Carbon Nano Tubes?

What are CNT's?

Carbon Nanotubes (CNT) are rolled up tubes of Nano Graphene Platelets (NGP) of consistent high purity . CNT can be conceptualized as a one atom thick layer of graphene rolled into a seamless cylinder. CNT are allotropes of carbon, their lengths of 1 um to 1cm , with a diameter of 100 nm to .4 nm  gives a length to diameter ratio as large as 28,000,000 to 1 (approximately 1/50,000 of the with of a human hair). They are members of the fullerene structural family.
