| Abstract | Morphological, rheological and mechanical properties of various biodegradable poly(butylene succinate)(PBS)/poly(butylene adipate-co-terephthalate) (PBAT) blends via conventional melt blending technique are studied. The morphology, rheology, and tensile properties of the PBS/PBAT blends were observed by scanning electron microscope (SEM), rotational rheometer, and universal testing machine, respectively. The SEM micrographs of the PBS/PBAT blends reveal an occurrence of phase separation indicating by a presence of spherical particles/cavities for a range of 10 to 30 wt% (i.e. PBS90-PBS70), and 70 to 90 wt% (i.e. PBS30-PBS10) PBT content and co-continuous structure for a range of 40 to 60 wt% (i.e. PBS60-PBS40) PBAT content. The rheological observation reveals that storage modulus (G'), loss modulus (G''), and complex viscosity (?*) for the PBS/PBAT lends exhibit similar tendency. The morphological properties of the blends appear to affect the tensile behavior of the PBS/PBAT blends. |
