Description

  • 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
  • Application: Bundles of MWNTs were trapped and manipulated to form nanotube ropes using optical tweezer.[1] 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.[2]
  • Physical form: Approximately 5-20 graphitic layers. Contains approximately 10-40% tubes, the remainder being multi-layer polygonal carbon nanoparticles and amorphous and graphitic carbon nanoparticles.
  • Preparation Note: Electric Arc Discharge Method
  • Other Notes: We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.
