Abstract

In this work, the effect of NE plasma treatment generated by radio-frequency was investigated in acid-base surface values, ion adsorption characteristics, and surface free energies of carbon blacks. As the results, it was clearly found that the obvious improvement of the treatment is in the London dispersive component (${\gamma}s^L$) of surface free energy of carbon blacks. Also both electron-acceptor ( ${\gamma}s^+$) and -donor (${\gamma}s^-$) parameters for the specific component (${\gamma}s^{sp}$) were also increased with increasing the treatment time, resulting in increasing the surface functional groups of the carbon blacks studied, together with a consequence of the increases of acidic and basic surface functional groups, ion exchange, zeta potential, and ion mobility.
