The effect of geometrical confinement on the interaction between charged colloidal suspensions

E.Allahyarov, H.L\"owen, I.D'Amico

Confinement between like-charged plates turns the force on colloids from repulsive to attractive at short distances under strong coupling.

Claims

C1strongest claim

Under strong coupling conditions, however, the sign of the force depends on the distance to the plates and on the interparticle distance. In particular, the particle-plate interaction becomes strongly attractive for small distances which may explain the occurrence of colloidal crystalline layers near the plates observed in recent experiments.

C2weakest assumption

The primitive-model electrolyte with the chosen charge and size ratios faithfully reproduces the strong-coupling regime of real confined colloids; no explicit solvent or surface chemistry is required.

C3one line summary

Simulations find distance-dependent attractions between confined like-charged colloids and walls under strong Coulomb coupling, offering a possible mechanism for wall-adjacent crystal layers.
