Abstract

We propose the quantitative method of evaluating the purity of multiwall carbon nanotubes (MWCNTs) using Raman spectroscopy. High purity MWCNTs were prepared by chemical vapor deposition (CVD) to be used as a reference material with 100% purity. Since the intensity and wavenumber ofD′′-band located at around 1500 cm−1were found to be independent of the excitation wavelength of a laser, the purity of MWCNTs was measured by comparing the intensity ratio ofD′′-band toG-band (ID′′/IG) of the sample with that of a reference material. The established method was verified by testing the mixture of amorphous carbon particles and reference MWCNTs.
