A lightweight material made from carbon nanotubes that is stronger than steel, and conducts almost as well as aluminium, has been unveiled by a start-up company in the US. The material could lead to lighter bulletproof clothing, wiring for aircraft and more efficient power-transmission lines, the company claims.
Researchers have long known that carbon nanotubes have extraordinary strength, transmit heat well and can act as semiconductors, depending on the method of construction. But these properties are of limited value in individual tubes and making bulk material with the same properties has not proved easy. Now Nanocomp, a start-up based in New Hampshire, US, has figured out a way round the problem.
