Abstract

Nanotubes in a bundle tend to bunch as a consequence of van der Waals attraction and their extremely high surface to volume ratio. In this article we demonstrate that they cannot be separated by applying an arbitrary large longitudinal tension. Thus, cooperation between nanotubes in a bundle is guaranteed, even under large tension. Such a finding could have an important role in designing self-assembled macroscopic nanotube-based cables.
