Abstract (AI)
We report a simple process to solubilize high weight fraction single-wall carbon nanotubes in water by the nonspecific physical adsorption of sodium dodecylbenzene sulfonate. The diameter distribution of nanotubes in the dispersion, measured by atomic force microscopy, showed that even at 20 mg/mL ∼63 ± 5% of single-wall carbon nanotube bundles exfoliated into single tubes. A measure of the length distribution of the nanotubes showed that our dispersion technique reduced nanotube fragmentation.
Key Findings
1
At a concentration of 20 mg/mL, approximately 63 ± 5% of single-wall carbon nanotube bundles exfoliated into individual tubes.
2
Atomic force microscopy was used to characterize nanotube diameter distributions in the aqueous dispersion.
3
Sodium dodecylbenzene sulfonate physically adsorbs nonspecifically to solubilize high weight fractions of single-wall carbon nanotubes in water.
4
The dispersion process reduced nanotube fragmentation, preserving nanotube length more effectively.
