A new study in Science reports that adding a chemical to carbon nanotube bundles increases their current capacity to approach that of copper, though the enhanced conductivity is not yet stable.
The research focuses on using electron-donating dopants to overcome the limited free electrons in metallic nanotubes, a key barrier to their practical use in electronics.
While long, pure metallic nanotubes remain difficult to produce, this discovery suggests a promising direction for developing carbon nanotube conductors with improved performance and longer shelf life.
