CONTROLLED PRODUCTION OF DOUBLE EMULSIONS USING MULTI-STEP DROPLET BREAK-UP

摘要

We propose a novel technique for producing monodisperse double emulsions using T-shaped microchannels. Control of the flow conditions produces variations in internal/external droplet sizes and in the internal droplet number. Both water-in-oil-in-water (W/O/W) emulsions (with 2 types of internal droplets), and oil-in-water-in-oil (O/W/O) emulsions were successfully prepared.
