Abstract/Summary Double emulsions are complex systems of an emulsion within an emulsion, where the droplets of the dispersed phase themselves contain even smaller dispersed droplets. They have significant potential in many applications, including pharmaceuticals, foods, cosmetics, microspheres, microcapsules and chemical separations. Recently, we have developed a mass-transfer method for making multiple emulsions using simple microfluidic devices. We have shown that a T-junction microfluidic device can generate double emulsions having either a single internal droplet or many fine droplets, and even triple emulsions. For expanding the application of this microfluidic method, we have transfered this method from microfluidic system to bulk solutions. Double emulsions were prepared by adapting this one-step solvent shift method to bulk. The influence of solvent system (including the dispersed phase, the continuous phase and the co-solvent, and their volume ratio), preparation method (sonication, homoginization, etc.) and surfactant were investigated. The formation mechanism and the stability of the double emulsions prepared were also explored.
