Temperature and composition induced morphology transition of Cerberus emulsion droplets.

Hypothesis: Various advanced geometries are endowed by the unique structure of "three rooms" of immiscible oils composing the Cerberus droplets. Adjustable interfacial properties and tunable volume ratio in the four-liquid system render it possible to realize the controlled morphology transition by the variation of temperature and emulsion composition.

Experiments: Cerberus emulsions are prepared in batch scale by traditional one-step vortex mixing, employing the oil combinations of methacryloxypropyl dimethyl silicone (DMS)/2-(perfluorooctyl) ethyl methacrylate (PFOEMA)/vegetable oil (VO).
