Improved arc discharge setup for synthesis of single and multi walled carbon nanotubes

Abstract

This paper presents development of a laboratory scale setup for production of CNTs by arc discharge process in an argon gas environment. The main problem with existing lab scale production is the cleaning of the chamber which is resolved in presented work by placing a circular metal sheet inside the chamber which is removed after the synthesis, thus allowing easy cleaning and recovery of the CNTs. The most noteworthy feature of the presented setup is its low cost, offering for the first time the synthesis of economical CNTs on small scale. In addition to offering better control over operating conditions, another unique feature of the developed setup is its capability to synthesize SWCNTs and MWCNTs with versatile range of diameters.
