Synthesis of Monodisperse Microparticles from Non-Newtonian Polymer Solutions with Microfluidic Devices

摘要

Microfluidic devices can form emulsions that are highly uniform in size;they can also form compound emulsions, in which each supradroplet contains exactly the same number of internal droplets, packed in exactly the same configuration.Because the drops can be formed with a highly controlled structure and uniformity, they are useful as templates to synthesize monodisperse particles. In such a process, microfluidic devices are used to form droplets with the desired structure, which are then solidified to produce particles. This allows synthesis of particles with a variety of shapes, including Janus particles, nonspherical dimers, and core-shell capsules.
