Shape‐Changing Multiphase Microparticles from Complex Liquid Crystal Emulsions
Advanced Functional Materials, EarlyView.Liquid crystalline network (LCN) microparticles are prepared from single, double (Janus), and triple emulsions through a simple and scalable bulk‐emulsification strategy. Under heating, the particles exhibit robust, reversible, large‐amplitude deformations that depend both on the morphology and the liquid crystals director field configuration.
