Structural correlations and phase separation in binary mixtures of charged and uncharged colloids

Elshad Allahyarov, Hartmut Löwen

Lower dielectric solvents drive charged-uncharged colloid mixtures to phase-separate into charged-rich and uncharged-rich fluids, an effect absent from DLVO theory.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

For lower dielectric contrast the increasing Coulomb coupling results in strong deviations and a fluid-fluid phase separation into charged-rich or uncharged-rich regions which is not reproduced by DLVO theory.

C2weakest assumption

The primitive-model representation with explicit microions and the chosen system sizes and salt concentrations are sufficient to capture the equilibrium phase behavior of real aqueous or low-dielectric suspensions.

C3one line summary

Primitive-model simulations find DLVO theory quantitatively accurate for structural correlations only at high dielectric constant and predict a fluid-fluid demixing transition absent from DLVO at lower dielectric constant.
