Electric double layer of anisotropic dielectric colloids under electric fields

Abstract: Anisotropic colloidal particles constitute an important class of building blocks for self-assembly directed by electrical fields. The aggregation of these building blocks is driven by induced dipole moments, which arise from an interplay between dielectric effects and the electric double layer. For particles that are anisotropic in shape, charge distribution, and dielectric properties, calculation of the electric double layer requires coupling of the ionic dynamics to a Poisson solver. We apply recently propos… Show more

“…The particles move slightly upwards or downwards along the ring because the length of the equator changes as the droplet changes its shape. We note that because the PS particles’ dielectric properties are similar to those of the oils, we do not observe particle alignment due to the particle-particle dipolar interactions (within the range of E -field strengths used here), as was the case when we used other particles, such as silver spheres [ 4 ] or clay minerals [ 25 , 26 ].…”

“…Patchy structures comprise at least two components with different functionalities; therefore, they possess interesting properties. For example, owing to specific interactions between patches, patchy structures can either self-assemble into complex structures or specifically adhere to a surface [ 1 , 2 , 3 ], guided–align [ 4 , 5 , 6 ], or self–propel [ 7 , 8 , 9 ]. Patchy capsules can additionally be used for storage, transportation, and release of cargo species [ 10 ].…”

“…In recent times the experimental importance of such objects has steadily risen. Increasingly experiments study dispersions of colloidal particles of a common, asymmetric shape [17][18][19]. These bodies may be unevenly charged.…”

“…In this paper, we apply the iterative dielectric solver (IDS), a recently developed fast BEM-based dielectric algorithm optimized for MD simulations, 34,35 that has been demonstrated to be competitive to imagebased methods, 36 to study the structured interfaces. The IDS has been applied to study complicated dielectric geometries such as patchy colloids 37,38 and self-assembly in binary suspensions. 33 The surface structures that are of interest have nanoscale dimensions, making first-principle or all-atom simulations infeasible.…”
