Solution

Carbon nanotubes represents one of the best examples of the novel nanostructures derived by bottom-up chemical synthesis approaches. Nanotubes have the simplest chemical composition and atomic bonding configuration but exhibit perhaps the most extreme diversity and richness among nanomaterial in structure and structure-property relations. The different

types of carbon nanotubes are as follows;

1. SINGLE WALLED NANOTUBES.
SWNTs are an important variety of carbon nanotube. In SWNTs have different chiralities of carbon nanotubes that include Armchair, Zigzag, Chiral. These can be easily twisted. SWNT synthesis requires catalyst.

2. MUL Tl WALLED NANO TUBES.
Mu/ti-walled nanotubes {MWNTs) consist of multiple rolled layers (concentric tubes) of graphene. This types of CNT's cannot be easily twisted. Purity of MWNT is high also can be easily produced without catalyst.
