Characterization of MWCNT in Dry Powder Form. Characterization of multi-walled carbon nanotubes was determined using electron
microscopy and Raman spectroscopy. (A & C) The diameter of the MWNCTs was determined
by measuring individual nanotubes visualized by TEM. (B) This SEM image shows a bundle
of MWCNTs, with individual nanotubes indicated by arrows. The length of individual
nanotubes was determined to be several μm long using SEM. (D) The Raman spectrum of
MWCNT obtained using 514.5 nm laser excitation. The presence of strong disorder band
(ID/IG peak ratio) suggests the existence of structural defects as determined by Raman spectroscopy.
