Drops fully covered by particles, so called Pickering emulsion drops, are used to stabilize emulsions and are ideal templates for producing particles and advanced capsules. Recent studies show how electrohydrodynamic circulation flows in drops can structure free particles on their surfaces. In this article, we study the structure of Pickering drops subjected to DC E-fields. Due to its effects, we observe plastic (irreversible) deformation of the two-dimensional granuar solid covering the droplet, including particle reorganisation similar to the “grain layer gliding” and “block gliding” typical of jammed granular matter.
