The interaction between two charged plates in electrolyte solutions

The HNC theory has been used to study the double-layer interaction between two charged plates immersed into a restricted primitive model electrolyte, under a wide variety of boundary conditions. It is found that the unbalance of the surface charge density on different sides of the plate may cause dramatic change in the behavior of the interaction force. The local electroneutrality will not be valid, and there exits strong correlation between the electrolyte inside the slit and that outside it.
