Charged Colloids at the Metal–Electrolyte Interface

We discuss the peculiarities of structure interface between a metal and stable colloidal dispersion charged nanoparticles in an electrolyte. It is demonstrated that quasi-2D ionic elevated density arises its vicinity due to effect electrostatic image forces. The stabilized particles, being electroneutral spatially distributed objects bulk electrolyte approaching interface, are attracted it. In their turn, counterions forming coat partially retract into 2D-layer, which results acquisition by particle effective charge eZ*≫e which, together with mirror image, creates electric dipole. formed dipoles, possessing moments directed perpendicularly form gas repulsion particles. intensity this repulsion, evidently, depends on value eZ* acquired nanoparticle having lost number counterions. can be related excess osmotic pressure Posm measured experiment.
