The Effect of Poly(Ethylene succinate) on Mechanical Property of PLLA/PES Composite in the In Vitro Degradation Process

Poly(L-lactide)/poly(ethylene succinate)(PLLA/PES) composites were prepared via melt-blending. The bending properties of PLLA/PES composites and PLLA materials were determined. And the effect of degradation time on mechanical properties of PLLA/PES composites and PLLA were too discussed. The results show that the degradation rate of PLLA/PES composites is faster than that of PLLA materials, especially after the degradation time of 12 weeks.
