Fig. 7

Zeta potential of pristine and oxidized MWCNTs in different electrolytes (a) and for dispersions of pristine nanotubes at different electrolyte concentration (b). Figure represents dependences of zeta potential on pH of electrolytes with different cation (NaCl, KCl, CsCl) and anion (NaCl, NaClO4) size. Concentration of nanotube dispersion is 0.2 mg/ml, electrolyte concentration is 0, 1, 0.01, and 0.001 mol/l, and sonication time for all dispersion was 3 min
