Abstract
The effects of chemically modified thermoplastic starch (CMPS) on the morphology, thermal and mechanical properties of the blends of poly (lactic acid)(PLA) and poly(butylene adipate-co-terephthalate)(PBAT) were studied. Blends of PLA/PBAT with the CMPS contents of 10, 20 and 30 wt% on the basis of PLA/PBAT weight were prepared by a twin screw extruder. The morphology, thermal and mechanical properties of the blends were examined by using scanning electron microscope (SEM), differential scanning calorimeter (DSC) and a tensile tester. The DSC study revealed that PLA/PBAT blends are thermodynamically immiscible, while the compatibility was much improved by addition of the CMPS.
