Comelcan stands for Coupled mechanical and electronic properties of carbon nanotubes bases systems.

The network consists of seven research groups in four European states, France, Germany, Ireland and Spain. One major aspect of the network is the training of young researchers, giving them the opportunity to work or study abroad.

In the last years, the remarkable electrical and mechanical properties of carbon nanotubes has triggered intense research of physicists, chemists and engineers.

Nanotubes can show the electric properties of either semiconductors or metals depending on their configuration. These properties alone make them very interesting for industrial applications ("molecular wires", nanotube transistors,...) as well as for fundamental research ("1-dimensional metals").

Nanotubes have also very interesting mechanical properties. They are very stiff and don't break easily when compressed. They bend and develop kinks, but those deformations are elastic: they will disappear when the pressure is released.


The aim of the network is research on the electrical and mechanical properties of single wall carbon nanotubes(SWNT). Objectives are, firstly, to get a clear understanding of the growth of nanotubes in various production methods with the aim to be able to control diameter and chirality. Secondly, the development of composite materials of SWNT. Thirdly, to understand the correlation of mechanical and electrical properties of SWNT. And finally, to apply the results of the fundamental research to develop new technologies based on SWNTs.
