The
complex structure of carbon nanotubes allows it to maintain certain properties
such as electrical and thermal conductivity as well as mechanical strength. In
order to obtain these complex structures and properties, however, the carbon
tubes need to be synthesized into their according structures. Chemical vapor
deposition is the most common technique, although other synthesis methods such
as arc discharge and laser ablation can be used. In chemical vapor deposition, vaporized
hydrocarbons are heated and decomposed by a metal catalytic substrate that
serves as a template for nanotube formation. The uniqueness of carbon nanotubes
extends far beyond their structures and properties, as their level of
compliance with different fields is vast. From building the darkest color to
providing a medium for tissue regrowth, there seems to be few boundaries for
these nanomaterials
