We have modified single walled carbon nanotubes (SWCNTs) with well defined matrix-based architectures to improve interface interaction in SWCNT composites.

 

Planting various functional groups on nanotube walls forms an extensive and important branch of nanochemistry of carbon tubes. 

 

Such a process can be performed by long-term treatment of tubes in acides,where the behavior of single-walled tubes was shown to depend on the method of their synthesis. Functional groups can be removed from the tube's walls by heating to temperatures above 623K.

 

An assumption that protonation of single-walled carbon nanotubes is assciated with the formation around a tube of an acidic layer 

that promotes its subsequent dissolution, was confirmed. XDS studies have shown that carbon nanotubes can serve as templates for sulfuric acid crystallization. This fact is considered as a direct evidence of its protonation.

 

The use of carbon nanotubes involves preparation of their uniform dispersions. For single-walled nanotubes, this can be achieved 

by either wrapping the tubes with polymers, Moreover, it was demonstrated that the reduction of single-walled nanotubes with alkali metals produced polyelectrolyte salts soluble in polar organic solvents such as dimethylsulfoxide.
