Particle Rafts and Armored Droplets

Particles floating at interfaces are commonly observed in nature, as well industrial processes. When the particles non-Brownian particles, large deformations of interface created that induce long-ranged capillary interactions and lead to formation particle rafts with unique characteristics. In this review we discuss recent efforts investigating raft role rafts’ own weight during dynamic clustering. Under specific conditions, these can ultimately collapse sink. subjected external or internal forces, undergoes test mechanical characteristics interfacial composite material. It behave a continuous elastic sheet under compression, although its discrete nature also trigger fragmentation via interparticle interactions. Finally, armored droplets, drops covered by protective shell lose their integrity when submitted deformations, resulting ejection fracturing armor. Open questions understand properties material highlighted future research fundamental physics rafts, customization cluster formation, disassembly collective is suggested.
