With the growth of single-use plastic production, the need for biodegradable polymers has increased to reduce plastic wastes. polylactic acid (PLA) has excellent tensile strength as well as biodegradable ability. However, the stiffness of PLA is an obstacle to widen its application such as plastic bag, packaging, and carriers. In this study, poly(butylene adipate-co-terephthalate) (PBAT), an elastic biopolymer, was blended with PLA to improve mechanical property adding poly(butyl acrylate) (PBA) as a compatibilizer. Morphology, mechanical and dynamic viscoelastic properties according to the different content of compatibilizers were analyzed by UTM, FE-SEM and DMA. As a result, it can be applied to a green material such as eco-friendly packaging, coating and disposables. |
