# Intermolecular forces in Carbon Nanotubes?

What are the intermolecular forces that can be found in Carbon Nanotubes?

• I am unfortunately not really getting what you are asking. Are you asking about the bonds between the carbons, or the forces that are inside a nanotube, or are you asking about the molecular forces between nanotubes? It would not hurt if you could expand your question a little. – Martin - マーチン Oct 8 '14 at 14:03

There is known, but poorly understood $\pi-\pi$ stacking. While weak compared to covalent, dipole or ionic interactions, it still beats usual van-der-vaals interactions.
Carbon nanotubes are, essentially, polycondensed aromatical systems, so they can and would interact with each other as aromatic systems via $\pi-\pi$ stacking
• To be fair, $\pi-\pi$ stacking are often considered one type of dispersion interactions. Since large conjugated systems like nanotubes have very high polarizabilities, the dispersion interactions are fairly large. – Geoff Hutchison Oct 10 '14 at 2:27
