Abstract
This study delves into the physical and chemical blending of polylactic acid (PLA) and poly(butylene succinate-co-adipate) (PBSA), utilizing supercritical fluid-assisted injection molding. The research focuses on studying how the blend interphase influences the formation of unique bimodal cellular structures, thereby improving PLA’s mechanical properties. Employing scanning electron microscopy (SEM) and tensile testing, the study examines the correlation between cell morphology and mechanical strength. The research highlights the influence of compatibilization and cell size distribution leading to a increase in crystallinity and mechanical stiffness of the foams, offering critical insights for enhancing Microstructure-Process-Property (MP2) relationships for automotive and aerospace materials.
