Bouncing oil-in-water compound droplets on superamphiphobic surfaces
We demonstrate that adding an immiscible oil core into impinging water droplets can strongly dampen the surface capillary wave propagation, which suppresses the air bubble entrapment in droplet impact on superamphiphobic surfaces at low Weber numbers; but instead, it facilitates the entrapment of a water drop, resulting in complex water-in-oil-in-water droplet configuration after rebound.
