Understanding depletion induced like-charge attraction from self-consistent field model

Pei Liu、Manman Ma、Zhenli Xu2015-07-17arXiv (Cornell University)

The interaction force between likely charged particles/surfaces is usually repulsive due to the Coulomb interaction. However, the counterintuitive like-charge attraction in electrolytes has been frequently observed in experiments, which has been theoretically debated for a long time. It is widely known that the mean f…
