Abstract
Raman spectroscopy has been utilized to show the increase of single walled carbon nanotubes (SWCNTs) content in commercial grade samples synthesized by the chemical vapour deposition (CVD) technique with a minimization of impurities using both hydrochloric acid treatment and surfactant purification. Surfactant purification methods proved to be the most effective, resulting in a three fold increase in the percentage of SWCNTs present in the purified product as determined by Raman spectroscopy.
