Abstract

In this study, the blends with weight ratio of 75/25 (w/w) were prepared where amorphous polylactide (PLA) was the matrix and poly[(butylene adipate)-co-terephthalate] (PBAT) or poly[(butylene succinate)-co-adipate] (PBSA) were the minor phases. Various blend morphologies could be obtained by using different molecular weight PLAs as well as different processing techniques (i.e., internal mixer and twin-screw extruder). Different microcellular bead foam structures ranging from low-density open-cell to high-density closed-cell could be manufactured not only via using blends with different droplet morphologies but also by using different minor phase solid inclusions with different rigidities originated from their different crystallization behavior.
