The packing density of the self-assembled, aligned carbon nanotubes can be controlled
through the incubation time.
Lan
et al.
[52] have reported an approach for vertically aligning multi-wall carbon
nanotubes on diverse substrates treated with polyelectrolyte. The shortened multi-wall
carbon nanotubes were fi rst functionalized with acyl chloride in thionyl chloride (SOCl
2
).
