  Stabilization and dispersion of electrical charge by colloids in non-polar
media, such as nano-particles or inverse micelles, is significant for a variety
of chemical and technological applications, ranging from drug delivery to
e-ink. Many applications require knowledge about concentrations near the
solid|liquid interface and the bulk, particularly in media where colloids
exhibit spontaneous charging properties. By modification of the mean field
equations to include the finite size effects that are typical in concentrated
electrolytes along with disproportionation kinetics, and by considering high
potentials, it is possible to evaluate the width of the condensed double layers
near planar electrodes and the bulk concentrations of colloids at steady state.
These quantities also provide an estimate of the minimum initial colloid
concentration that is required to support electroneutrality in the dispersion
bulk, and thus provide insights into the quasi-steady state currents that have
been observed in inverse micellar media.
