Purification of Single Wall Carbon Nanotubes produced by thermal plasma

Raymor Industries is a Canadian high-tech company using thermal plasma technology to produce single-walled carbon nanotubes (SWCNTs) and graphene.
As synthesized, the SWCNTs inevitably contain carbon impurities and catalyst metal particles that must be removed to continue a separation process according to their electronic properties (metallic or semiconducting). Once purified and electronically separated, the SWCNTs can be integrated to vast potential applications including electronics, energy, medicine, batteries, etc.
The purification and separation processes of SWCNTs are conducted by NanoIntegris Technologies, a subsidiary of Raymor who is a world leading supplier of high purity, semiconducting, and metallic SWCNTs. NanoIntegris adapted a standard purification protocol which seems not being very effective. The literature review reveals that the purification protocols must be tailored according to the synthesis method, and there are no current references for thermal plasma processes. NanoIntegris needs to optimize their purification protocols to remain competitive as a world-leading provider of CNTs.
The laboratory of Prof. Richard Martel, an internationally recognized leader in the field of carbon nanotube electronics has the experience on material purification….
