초록

In this study, we investigated the effects of polylactic acid (PLA) blending on the mechanical properties (such as tensile strength, initial modulus, and elongation at break) of polybutylene succinate (PBS) for improving the associated tensile properties without incorporating compatibilizers. The maximum PLA mixing content of 20% by weight was selected by studying the mean squared displacement through molecular dynamics simulation. Subsequently, the PBS/PLA blends were compounded by increasing the PLA content from zero to 20% by weight. The obtained results indicate that the tensile strength of the PBS/PLA blend increases when the PLA blend content is 15% by weight, and the initial modulus increases when the PLA blend content is 20% by weight. Furthermore, at the content of approximately 15% by weight, PLA can be blended without a compatibilizer for improving the tensile strength and initial modulus.
