Résumé

Droplets and bubbles coated by a protective armour of particles find numerous applications in encapsulation, stabilization of emulsions and foams, and flotation techniques. Here we study the role of a body force, such as in flotation, as a means of continuous encapsulation by particles. We use dense particles, which self-assemble into rafts, at oil-water interfaces. We show that these rafts can be spontaneously or controllably destabilized into armoured oil-in- water droplets, which highlights a possible role for common granular materials in environ- mental remediation. We further present a method for continuous production and discuss the generalization of our approach towards colloidal scales.
