Improving Crystallization Properties, Thermal Stability, and Mechanical Properties of Poly(L-lactide)-<i>b</i>-poly(ethylene glycol)-<i>b</i>-poly(L-lactide) Bioplastic by Incorporating Cerium Lactate.

ABSTRACT: The more flexible and faster biodegradation rate of poly(L-lactide)-b-poly(ethylene glycol)-b-poly(L-lactide) (PLLA-PEG-PLLA) triblock copolymer makes it a promising bioplastic compared to PLLA. However, finding effective additives for this triblock copolymer remains a research challenge for their wider applications. This work involved the melt-blending of a cerium lactate (Ce-LA) antibacterial agent with a triblock copolymer. The thermal properties, crystalline structures, mechanical properties, and phase morphology of the PLLA-PEG-PLLA/Ce-LA composites were examined. With 0.5 wt% Ce-LA, the composite exhibited the best crystallization properties. The crystallinity of the composite contained 0.5 wt% Ce-LA increased from 11.8 to 15.9%, and the half-time of crystallization dec
