Visualization of droplet break-up in pre-mix membrane emulsification using microfluidic devices

摘要

To investigate the break-up of emulsion droplets in pre-mix or dead-end membrane emulsification, a microscopic study was conducted in microfluidic devices. Channels with shapes such as constrictions, junctions, and combinations thereof representing ideal membrane structures where etched in silicon. Through these structures pre-mix emulsion droplets where Pushed, which was recorded with high-speed video microscopy.
