Abstract

Mechanical and morphological properties of poly(acrylonitrile-butadiene-styrene) (ABS) and poly(lactic acid) (PLA) blends containing compatibilizers were investigated. Poly(styrene-acrylonitrile)-g-maleic anhydride) (SAN-g-MAH), poly(ethylene-co-octene) rubber-maleic anhydride (EOR-MAH) and poly(ethylene-co-glycidyl methacrylate) (EGMA) were used as compatibilizers. Mechanical properties such as tensile, flexural and impact strengths of ABS/PLA (80/20, wt%) blends were found to be increased when the SAN-g-MAH, EOR-MAH and EGMA were used. The maximum values for mechanical properties of the ABS/PLA (80/20) blend were observed when SAN-g-MAH was used as a compatibilizer at the concentration of 3 phr. From morphological studies of the ABS/PLA (80/20) blends, PLA droplet size was decreased by the addition of the compatibilizers used in this study. From the results of mechanical and morphological properties of the ABS/PLA (80/20) blends, SAN-g-MAH (3 phr) was found to be the most effective compatibilizer among the compatibilizers used in this study.

본 연구에서는 poly(acrylonitrile-butadiene-styrene)(ABS)와 poly(lactic acid)(PLA)를 블렌드할 경우 상용화제의 효과에 의한 기계적 물성과 모폴로지 변화에 대하여 연구하였다. 상용화제로는 poly(styrene-acrylonitrile)-g-maleic anhydride) (SAN-g-MAH), poly(ethylene-co-octene) rubber-maleic anhydride(EOR-MAH)와 poly(ethylene-co-glycidyl methacrylate) (EGMA)를 사용하였다. ABS/PLA 블렌드의 인장강도, 굴곡강도 및 충격강도를 포함한 기계적 강도 측정 결과 SAN-g-MAH, EOR-MAH 그리고 EGMA 상용화제 모두 기계적 강도가 향상되는 것을 관찰할 수 있었다. 이중에서 SAN-g-MAH를 사용하였을 때 가장 우수한 기계적 강도를 나타내었으며, 3 phr 함량에서 가장 높은 수치를 나타내었다. SEM 모폴로지의 경우 세 종류의 상용화제 모두 ABS/PLA 블렌드에서 PLA의 droplet 크기가 감소하는 것을 알 수 있었다. 요약하면, 블렌드의 기계적 물성과 모폴로지 측정 결과 ABS/PLA블렌드에서 세 종류의 상용화제중 SAN-g-MAH (3 phr) 첨가하였을 때 가장 우수한 상용화제로서의 역할을 하는 것을 알 수 있었다.
