Quantifying the Aggregation Factor in Carbon Nanotube Dispersions by Absorption Spectroscopy
Figure 2
Absorbance spectra of SWCNT dispersions in (a) NMP and (b) IPA for 60 μg/mL ((i) and (ii)), 30 μg/mL ((iii) and (iv)), and 15 μg/mL ((v) and (vi)) after 20 minutes sonication only ((i), (iii), and (v)) and after 20 minutes sonication followed by centrifugation ((ii), (iv), and (vi)).
