Spectroscopic evaluation of individually dispersed single-walled carbon nanotubes
2013
Najeeb, Choolakadavil Khalid | Kim, Duckjong
We prepared the individually dispersed solutions of various single-walled carbon nanotubes (SWCNTs) synthesized by electric arc discharge, catalytic chemical vapor deposition, and high-pressure carbon monoxide process using the biocompatible chitosan derivative, chitosan hydroxyphenylacetamide, and evaluated their dispersion efficiencies. We propose a new spectroscopic parameter for quantitative evaluation of the individually dispersed SWCNTs and present the optimum SWCNT-to-dispersant ratio for high-quality dispersion of each SWCNT type based on the proposed parameter.
