반응성 사슬 연장제를 이용한 PLA/PBAT 블렌드의 상용성

초록

This study aims to improve the brittleness of polylactic acid (PLA) by blending it with poly(butylene adipate-co-terephthalate) (PBAT), which has higher flexibility. A reactive chain extender containing epoxy groups was synthesized and incorporated at various concentrations to enhance the compatibility between the two polymers. The thermal, mechanical, and morphological properties of the resulting blends were analyzed. The addition of the chain extender led to moderate improvements in tensile strength and Young's modulus, while maintaining thermal stability. These results suggest that the chain extender offers a potential strategy for improving the properties of PLA/PBAT blends.
