基于富勒醇的单根碳纳米管分散液的制备及表征
Preparation and characterization of the dispersed individual carbon nanotubes solutions based on fullerenols
摘要
Abstract
Multi-walled carbon nanotubes (MWCNTs) were purified by using 4 kinds of liquid phase oxidation step methods, and purified MWCNTs were dispersed by using fullerenol as surfactant. Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), and Raman spectroscope characterizations indicate that liquid phase oxidation step purifying method by using NaOH-mixed acid is the most effective method for MCNTs refinement. It not only could remove the impurities in MCNTs, but also could functionalize the surface of MCNTs with hydroxyl and carboxyl groups. SEM images confirm that the fullerenol surfactant can greatly improve dispersion of the purified MWCNTs, homogenous dispersions of individual MWCNTs can be prepared in the experiment.关键词
