    Multi Walled Carbon Nanotubes - Nanografi Nano Technology

    Multi-walled carbon nanotubes are used in Chemical area: Multi-walled carbon nanotubes are an allotrope of sp2 hybridized carbon like graphite and fullerenes , hence possess great chemical stability. Be that as it may, one can functionalize the nanotubes to make composites strong and dispersible.

    Multi-walled carbon nanotubes (MWCNTs) are elongated hollow cylindrical nanoobjects made of sp2 carbon. Their diameter is 3–30 nm and they can grow several cm long, thus their aspect ratio can vary between ten and ten million. The wall thickness of a MWCNT is fairly constant along the axis, and therefore the inner channel is straight.

    Carbon nanotubes (CNTs) have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches

    Single-walled carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs) are similar in certain respects but they also have striking differences. SWNTs are an allotrope of sp2 hybridized carbon similar to fullerenes. The structure is a cylindrical tube including six-membered carbon rings similar to graphite.
