dc.description.abstractPoly(lactide)(PLA)에 이산화탄소가 원료로 합성된 poly(ethylene carbonate)(PEC) 10 mol%을 블렌딩하여 용융압출 공정으로 쉬트를 제조하고 일축방향으로 연신하여 다양한 연신비로 필름을 제조하였다. 이 필름의 연신비에 따른 구조적 특성을 확인하고, 기계적, 열역학적, 물성 및 차단성을 연구하였다. PLA/PEC 블렌딩 쉬트 및 필름은 α' 상을 가지며, 연신비가 증가할수록 더 높은 결정화도와 배향도를 나타낸다. 따라서 연신비가 증가할수록 필름의 물성도 향상된다. PLA에 비결정성 수지인 PEC를 블렌딩함으로써 전반적으로 기계적인 강도는 다소 감소하였지만, PLA의 단점인 유연성과 차단성이 향상되었다. 본 연구에서 제조한 PLA/PEC 블렌딩 필름은 환경 친화적인 유연한 포장 필름으로의 실용화가 가능할 것으로 기대된다. From poly(lactide) (PLA) and poly(ethylene carbonate) (PEC) synthesized using CO2, a PLA/PEC blending film is prepared by melt extrusion and then drawn to uniaxial orientation with various draw ratios. The structural conformation was confirmed and the mechanical, thermal and barrier properties were investigated. It was confirmed that the PLA/PEC blending sheet and films were composed of alpha' phase form. The strain-induced crystallization and molecular orientation of PLA/PEC films of alpha' phase increased with increasing the draw ratio. It improves the physical properties of the film. With amorphous PEC blending, the mechanical properties of PLA/PEC blending films were slightly lower than those of net PLA films, however, the flexibility and bather properties were higher. In this study, the PLA/PEC blending film is expected to be commercialized as an ecofriendly flexible packing film.en_US
