Abstract
The effects of confining walls and many-body forces on charge-stabilized colloidal suspension are calculated using ab initio density functional theory. A Derjaguin-Landau-Verweg-Overbeek pair-potential interaction describes the results quantitatively, with small adjustments to the parameters. We find no evidence for three-body effects or any attraction between colloidal particles with like charges.
