제목 Enhancement of Mechanical Property and Dynamic Viscoelasticity by Improving Interfacial Interaction of PLA/PBAT Composites
초록 Environmental pollution caused by the increment of the disposable plastic wastes stirs up interest in biodegradable polymers. Polylactic acid (PLA) and poly(butylene adipate-co-terephthalate) (PBAT) which have an excellent biodegradability and productivity are a representative biodegradable polymer. However, poor compatibility of PLA and PBAT blend has been considered as the biggest problem to adopt the blend as a commercial products. In this study, poly(butyl acrylate) (PBA) and a modified siloxane polymer were added as compatibilizers. As a result, the mechanical and thermal properties were improved and they were confirmed through UTM, FE-SEM, and DMA analysis. Therefore, it can be applied as a sustainable packaging or disposable materials for the sustainable future.
