Carbon Nanotube

Arc-produced, multi-walled carbon nanotubes contain 55-65 wt% nanotubes and 35-45wt% graphite nanoparticles. The tubes have a diameter distribution of 2-50 nm, and a typical length of >2 microns (straight tubes). The chemical composition is 100% carbon, with no metal impurities. Because the nanotubes are grown at very high temperatures (3000-4000°C), the product contain far less defects than nanotubes produced by other methods. The nanotubes are stable in air up to 700°C.

Arrays grown on 10x10x1mm quartz substrate using a single source CVD process that yields vertically aligned MWNTs (< 1% catalyst impurity). Arrays are 30µm tall (± 3µm) and are composed of MWNTs 100nm in diameter (± 10nm). Arrays up to 150µm in height can be provided on request.

These carbon nanotubes are produced via the Arc Discharge process and are purified via density gradient centrifugation.

Carbon nanotubes enhance the electrical conductivity and the mechanical properties. It is also used in chemical research. It is suitable as a hydrogen storage material. It is an ideal super capacitor electrode materials, It is used in the preparation of super composites. carbon nanotubes have excellent field emission performance and used in heavy weight cathode tube technology. It is also applied to naanometer electronic, catalytic fiber machine. Nanotubes will have an important role in nanotechnology engineering. carbon nanotube also can be used in making molecule bearings and nano robot.

Carbon nanotubes are synthesized via floating catalyst chemical vapor deposition (FCCVD) to control wall number, diameter, bundle size, and conductivity type, or produced as vertically aligned structures using inductively coupled plasma enhanced chemical vapor deposition (IC-PECVD)[2][3]. Catalytic chemical vapor deposition of methane in the presence of iron, molybdenum, or iron–molybdenum alloy thin-layer catalysts yields carbon nanotubes, a method also applied in the preparation of isolated single-walled variants[1][3].

This product has been enhanced for energy efficiency.
