Carbon nanotubes form bundles due to the van der Waals interaction. The properties of networks made from such bundles are dependent on the bundle properties (average number of parallel tubes inside a bundle D and the bundle length compared to the nanotube length lCNT), and not only on the usual parameters that define carbon nanotube networks, such as density and length of single nanotubes. Here we propose a model for random networks from carbon nanotube bundles and compare their properties with those of ordinary carbon nanotube networks.
