3.4 Fourier‑Transformed Infrared Spectroscopy (FTIR)
FTIR provides information about the impurities remaining from the nanotube
synthesis, the catalytic activity of CNTs [128], and the functional organic groups
attached during functionalization [124]. As an example, Fig. 5 presents two
Fig. 4 TEM images of oxidized MWCNTs at 200 kV (left), and aminopyrene–MWCNT π–π stacking
adducts showing open ends and aminopyrene adsorption (right). The image on the right was acquired
with a GRANDARM300cFEG microscope with corrective aberration in the objective lens
Fig. 5 FTIR spectra of pristine MWCNT (black), oxidized MWCNT (blue). Note peak at 1691 cm
−1 due
to C=O stretching and broad band at 3300 cm
