The particle size distribution in dispersions of pristine MWCNTs in NaCl solution at different pH. Graphs show the particle size distribution in dispersion of pristine carbon nanotubes (MWCNTin) (dispersion concentration of 0.2 mg/ml) in NaCl solution (C = 0.1 mol/l) at pH = 3.0 (a), pH = 7.7 (b), pH = 9.4 (c), and pH = 11.0 (d) before (1) and after sonication (2). Ultrasonic treatment was performed under ultrasound at 22 kHz during 3 min. The measurements were carried out in 1 min after sonication
