Abstract
PLA는 친환경 생분해성 플라스틱으로 식품용 포장재 및 3D 프린트용 필라멘트로 주로 사용되고 있다. 본 연구에서는 친환경 천연 충전재인 셀룰로오스 나노크리스탈(CNC)을 PLA에 충전한 복합재의 물성을 조사하였다. PLA/CNC 나노복합재는 용융혼합 및 압축성형에 의해 제조하였다. CNC의 함량에 따른 PLA/CNC 나노복합재들의 인장특성, 충격강도 및 열적 특성을 각각 측정하였다. CNC의 함량이 늘어날수록 나노복합재의 결정화도, 인장 강도 및 인장 탄성률은 증가하였지만 유리전이온도, 냉각결정화 시작 온도 및 파단 신율은 감소하였다. 충격강도는 CNC 1 phr일 때 가장 높았다.
