Attraction between like-charged colloidal particles induced by a surface a density - functional analysis
arXiv:cond-mat/9809191 · doi:10.1209/epl/i1999-00276-4
Abstract
We show that the first non-linear correction to the linearised Poisson-Boltzman n (or DLVO) theory of effective pair interactions between charge-stabilised, co lloidal particles near a charged wall leads to an attractive component of entro pic origin. The position and depth of the potential compare favourably with rec ent experimental measurements
