In order to improve the dispersion of multi-walled carbon nanotubes (MWCNTs), MWCNTs were physically modified by the surfactant of Poly (vinyl pyrrolidone) (PVP), cetyl trimethylammonium bromide (CTAB) and sodium dodecylbenzene sulfonate (SDBS), and were chemically treated by the acid oxidation. Measuring the zeta potential of the dispersions of modified MWCNTs and surface contact angle of modified MWCNT powders, influence of acting forces on the dispersions of modified MWCNTs was analyzed. The balance of electrostatic repulsion and van der Waals forces determines the stabilization of aqueous modified MWCNT dispersions. The sufficient reactive groups, ions and long molecular chains play important roles for such balance.
