Single-walled carbon nanotube of High-pressure carbon monoxide (HiPCO) method: 

HiPCO® is considered benchmark Nanotube and is used in applications where specific, repeatable properties are required.



At NoPo we have established the continuous process to manufacture single-walled carbon nanotubes of such small diameters in bulk.

G/D ratio: 24, RBM Peaks: 272, 228cm-1 Average diameter of the nanotubes is ~ 0.8nm

TGA Plot of NoPo HiPCO 

The material contains ~85% of carbon and ~15% of residue (non-carbonaceous impurity), estimated by the thermogram.


There is no significant weight loss around 100-200°C which indicates very less or no moisture content in the material.

Advantages offered by small diameter NoPo SWCNT


  • Smaller diameters are easier to disperse and stay in a dispersion longer.

  • Small Diameter Nanotubes have the highest tensile strength. 

  • SWCNT properties are precisely defined unlike MWCNT. This leads to a more consistent product. 

  • Fe is easy to remove using our proprietary Halogenation process. It is not practical to remove all the other catalyst components such as Co, Bimetal, etc. Present in other commercially available nanotubes.   

  • We have developed methods to functionalize and disperse Nanotubes in most common solvents. Due to high consistency of product. Results remain same from batch to batch.
