The phase behavior of chiral macromolecules is one the key subjects in chemistry, biology, and materials science. Here we take poly(L-lactic acid) (PLLA) mesomeric poly(D, L-lactic (mPLA) mixtures as a model system investigate separation behaviors double emulsion droplets. At high mPLA compositions, creates transient bicontinuous networks or discrete domains at liquid-liquid interface eventually generates eyeball-like microcapsules. low occurs first but trapped by lateral crystallization PLLA, leading to spindle-like dynamic pathways can be further modulated PLA-based amphiphilic block copolymers, so that microcapsules are configurable between eyeball-, spindle-, Janus-like structures. By comparing with on plane substrate, unveil dynamics interfaces significantly affected interfacial properties hydrodynamic effects. This work clarifies transition PLLA/mPLA sheds insight into for their structural modulation.
