In the case of covalent functionalization, the local stresses due to misalignment of 31 orbitals of carbon atoms with sp hybridization make the carbon nanotubes more reactive than a graphene sheet, facilitating covalent bonding of chemical species. However, even when extensive damage to the carbon nanotubes structure are avoided, a notable disadvantage of this process of functionalization is the breakdown of the conjunction of the carbon nanotubes in with the conversion of carbon with hybridization sp -sp (Han and Fina 2011). 

Although the ability of carbon to form multiwall tubular nanostructures is well known and these tubes have been studied extensively, much less information is available about carbon nanotube structures having polygonal cross sections. An occurrence of polygonal vapor-grown carbon fibers with a core carbon nanotube protrusion was noted by Speck et al. ° as early as 1989, but no details were given about core fiber structure and its polygonization.
