The amphiphilic particle having multi surface properties is one of the materials that are possibly used to separate the oil/water. By forming a stable paramagnetic Janus emulsion and polymerizing it, the functional particle can be fabricated. This particle absorbs oil from water and its motion is controllable by electromagnetic force. Even though a large advantage of these particles, the production of uniform Janus emulsion and continuous polymerization has been limited. To resolve this problem, we built a 3D printed microfluidic platform for monodispersed Janus emulsion mass production. The fabricated particle had an amphiphilic characteristic with bowl-like shape. We analyzed the relationship between capillary number and the particle diameter and observed the change of interfacial tension and morphology as the surfactant concentration changes. And we confirmed that the particles we fabricated adsorb the oil and are attracted to the permanent magnet. It is expected that mass-production of these Janus particles would be effective on enhance the efficiency of oil separation.
