Dispersion Efficiency of Carbon Nanotubes in Aqueous Solutions of Deoxycholate Sodium Salts

Abstract

We have used Raman in id PL spectroscopy in order to quantitatively estimate the abundance of isolated CNT's m as-sonicated samples in 1)00 aqueous solutions and the survival late of isolated CN'1's during an ultracentrifuge process All the PL, intensities in the as-sonicated samples increased almost linearly as the amount, of CNTs in the 1 wt,% D00 solution of 50 nil increased up to 10 mg The abundance of isolated CNTs III the as-somcated samples was approximately 76%; and the survival late of isolated CNTs during the ultracentrifuge process was similar to 50% on aye, age
