Tuning Patchy Bonds Induced by Critical Casimir Forces

WebApr 22, 2024 · We have shown that patchy colloidal fluid with three and four equivalent patches, confined in the attractive random porous media, undergoes the re-entrant gas–liquid phase separation, with the possibility for the liquid phase to have vanishing low density. This behavior is caused by an interplay between the strong colloid–colloid … Patchy particles are micron- or nanoscale colloidal particles that are anisotropically patterned, either by modification of the particle surface chemistry ("enthalpic patches"), through particle shape ("entropic patches"), or both. The particles have a repulsive core and highly interactive … See more Simulations The interaction between patchy particles can be described by a combination of two discontinuous potentials.
