Crystalline Poly(L‐Lactic Acid) Nanoparticles via Nonsolvent‐Induced Cascade Phase Separation

Journal of Polymer Science, EarlyView.
Water is used as the nonsolvent to induce liquid/liquid phase separation (LLPS) of poly(L‐lactic acid) (PLLA)/propylene carbonate solution and PLLA crystallization. Due to the two levels of cascade LLPS coupled with confined PLLA crystallization, three types of polymeric nanoparticles, including PLLA single crystals, Ouzo crystalsomes, and sheaf‐like ...
