Fine felted nanotubes - a new composite material made of carbon nanotubes

Carbon nanotubes (CNTs) either cannot be combined adequately with other materials, or if they can be combined, they then lose their beneficial properties. Scientists have now developed an alternative method, with which CNTs can be combined with other materials, so that they retain their characteristic properties.
