  • Semicrystalline polymers can crystallize in the unique crystalline polymorph and show different phase behaviors under the high-pressure CO2 treatment. Understanding such unique crystallization and phase transition behavior is of fundamental importance for the CO2-assisited processing of semicrystalline polymers. Herein, we investigated the polymorphic crystalline structure, phase transition, and structure-property relationships of poly(L-lactic acid) (PLLA) treated by CO2 at different pressures (1−13 MPa) and crystallization temperatures (Tc’s, 10−110 °C). PLLA crystallized in the PLLA/CO2 complex crystals under 7−13 MPa CO2 at Tc≤50 °C but the common α crystals under the high-pressure CO2 at Tc≥70 °C. Solid-state nuclear magnetic resonance analysis indicated that the PLLA/CO2 complex crystals possessed weaker interactions between the PLLA chains than the common α crystals. The PLLA/CO2 complex crystals were metastable and transformed into the thermally stable α crystals via the solid-to-solid route during heating or annealing at the temperature above 50 °C. The complex crystals of PLLA produced at low Tc was more ductile than the α crystals due to the lower crystallinity and the plasticizing effect of CO2.
