Synthesis and Purification of Arc-Grown SWCNTs

In 1997 Journet et al. (23) described a method to obtain high yields of SWCNTs by means of electric arc-discharge, using a transition metal mixture (Nickel and Yttrium) as catalyst. In a typical arc reactor, 

Tmr corresponds to the temperature of maximum rate of weight loss under air atmosphere at a heating rate of 5°C/min, and D to the average bundle diameter obtained by SEM micrographs. Polyetherimide (PEI) is the compatibilizing agent.
