Carbon nanotubes are extremely lightweight, electrically highly conductive, and more stable than steel. Due to their unique properties, they are ideal for numerous applications, including ultra-lightweight batteries, high-performance plastics and medical implants. However, to date, it has been difficult for science and industry to transfer the extraordinary characteristics at the nano-scale into functional industrial applications. The carbon nanotubes either cannot be combined adequately with other materials, or they lose their beneficial properties once combined. Scientists from the Functional Nanomaterials working group at Kiel University (CAU) and the University of Trento have now developed an alternative method, with which the tiny tubes can be combined with other materials so that they retain their characteristic properties. The research results have now been published in Nature Communications.
