Abstract
We determined with Canonical Monte Carlo simulations the spatial distribution of counterions released from discretely charged interfaces which form layered dielectric media, as simple models of either an aqueous thin film or a lipid membrane. The ions in a medium of low dielectric constant (membrane) experience a substantial condensation onto the charged interfaces forming a quasi-two-dimensional ionic double layer which induces attraction between the equally charged bounding surfaces. When the dielectric constant is increased (case of a thin film) there is a shift in the sign of the interaction between the interfaces, changing from attractive at short distances of their separation, towards repulsive for larger distances. At very high dielectric constant the force-distance curve always shows repulsion.
