Abstract Liquid-liquid phase separation plays an important role in many natural and technological processes. Herein. we implement lateral microphase separation at the surface of oil micro-droplets suspended in water to prepare a range of discrete floating protein/polymer continuous two-dimensional (2D) heterostructures with variable interfacial domain structures and dynamics.
