Steric stabilization stabilized nonaq

With high particle charges and low ionic concentrations, electrostatic repulsion (39,4C) alone should be capable of stabilizing, the colloid. This Typically occurs when surface potentials are around lOOmV. Steric stabilization (41,42) in nonaq-ueous media is important to achieve stability in weakly charged systems. Direct experimental measurements of particle-particle forces or potentials in nonaqueous media are not yet available.
