Optimizing the Dispersion Conditions of SWCNTs in Aqueous Solution of Surfactants and Organic Solvents

Figure 12

EFM analysis SWCNTs dispersed in water by DOC (10 mg/mL). (a) AFM image and (b) its corresponding Nap phase are shown. In the height tracing, nanotubes are wrapped by the surfactants where the Nap phase shows the presence of surfactants by phase difference. Presence of surfactants reduces phase as it changes surface properties of the CNTs.
