Abstract:

Fully biodegradable poly(butylenes succinate)/poly(butylenes adipate/terephthalate) (PBS/PBAT) blends were prepared via melt mixing. The melt flowability, crystallization behavior, mechanical properties, and compatibility of the blends were studied with MFR, DSC, XRD, SEM, and mechanical test. With increasing PBAT content, the tensile strength increased first and then decreased slightly, the impact strength decrease first and then increased, the elongation at break kept increased. When the loading of PBAT was 20wt%, impact strength increased by 82%, elongation at break increased by 1000%, tensile strength decreased only by 6%, compared with neat PBS.
