General description

Multi-walled carbon nanotube core surrounded by a fused carbon shell, the remainder being multi-layer polygonal carbon nanoparticles and amorphous and graphitic carbon nanoparticles.It contains approximately 5-20 graphitic layers. Carbon nanotubes produced by arc discharge technique contain very low impurity and possesses very high crystallinity. 4


Bundles of MWNTs were trapped and manipulated to form nanotube ropes using optical tweezer. MWNTs were calcined and sonicated to form carbon nanoribbons. The nanoribbons were used to fabricate array of 98 source and drain electrodes on a 300 nm SiO2/p++Si substrates.2 A MWNT probe was fabricated on Si cantilevers.
Carbon nanotube, multi-walled (MWNT) belongs to the class of carbonaceous materials with excellent physiochemical, thermo-mechanical and electrochemical properties. This material can be used in a variety of sustainable energy applications such as solar cells, photocatalysis, biosensor, gas sensor, supercapacitor and as a filler that acts as a reinforcement to improve the mechanical property of composites.
