Fabrication of Janus droplets by evaporation driven liquid–liquid phase separation

Abstract

We present a universal and scalable method to fabricate Janus droplets based on evaporation driven liquid–liquid phase separation. In this work, the morphologies and chemical properties of separate parts of the Janus droplets can be flexibly regulated, and more complex Janus droplets (such as core–shell Janus droplets, ternary Janus droplets, and multiple Janus droplets) can be constructed easily.
