초록
Poly(lactic acid)/poly(butylene adipate-co-terephthalate)(PLA/PBAT) 블렌드의 경우 PLA에 블렌딩된 PBAT의 함량이 커질수록 열안정성이 증가하였으며 CaCO3 첨가에 의한 storage modulus 값의 증가로 PLA/PBAT 블렌드의 강성이 향상되었음을 확인하였다. PLA/PBAT/CaCO3 블렌드의 크리프 변형 결과로부터 CaCO3가 증가할수록 더 낮은 온도에서 시편의 변형 저항성이 급격하게 감소하는 것을 확인하였다. 이로부터 60 oC 이상인 경우 PLA의 단독 사용보다 PLA/PBAT 블렌드를 사용하는 것이 변형에 대한 저항성이 클 것으로 생각된다.
In the case of poly(lactic acid)/poly(butylene adipate-co-terephthalate) (PLA/PBAT) blend, thermal stability increased as higher PBAT content was blended and it is confirmed that stiffness of PLA/PBAT blend has been improved by increasing the value of storage modulus as addition of CaCO3. From the creep test of PLA/PBAT/CaCO3 blends, the deformation resistance decreased rapidly at lower temperatures as CaCO3 increased. Thus, in the case of application at more than 60 oC, it was considered that PLA/PBAT blend has a high resistance to deformation than pure PLA.
