Аннотация:The effect of discrete charges embedded inside a dielectric film on the surface of an ionic substrate is examined. The analytical solution for the potential distribution is presented in the cases of diluted and concentrated electrolyte solutions. The image-charge contribution to the film stability is derived for charges randomly distributed at one of the film boundaries. It is shown that the image-charge component of the disjoining pressure can dominate over the other types of surface forces either for very thick films or for film thicknesses less than or comparable to the average charge separation.
