The Korea Institute of Science and Technology has, for the first time in the world, created and successfully tested an electric motor that uses carbon nanotubes instead of copper. In the course of the research, scientists found that it is possible to convert electricity into mechanical motion without the participation of metals.
Carbon nanotubes are cylindrical nanostructures arranged in a hexagonal lattice. They have high conductivity of both electric current and heat, but due to metal impurities remaining after production, they are almost never used in technology.
A team of Korean scientists managed to develop a new cleaning method, thanks to which they were able to obtain coils from nanotubes with high conductivity.
Scaling this technology will allow for more energy-efficient transport and electronics, as well as reduce the weight of motors and reduce the dependence of their price on copper prices.
