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

摘要：

We have used Raman and PL spectroscopy in order to quantitatively estimate the abundance of isolated CNTs in as-sonicated samples in DOC aqueous solutions and the survival rate of isolated CNTs 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％ DOC solution of 50 ml increased up to 10 mg. The abundance of isolated CNTs in the as-sonicated samples was approximately 76％, and the survival rate of isolated CNTs during the ultracentrifuge process was～50％ on average.
