| 中文摘要 | biodegradable polymer blends based on biosourced polymers, namely polylactide (pla) and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (p(3hb-co-4hb)), were prepared by melt compounding. the effects of p(3hb-co-4hb) on the miscibility, phase morphology, thermal behavior, mechanical properties, and biodegradability of pla/p(3hb-co-4hb) blends were investigated. the blend was an immiscible system with the p(3hb-co-4hb) domains evenly dispersed in the pla matrix. however, the tg of p(3hb-co-4hb) component in the blends decreased compared with neat p(3hb-co-4hb), which might be attributed to that the presence of the phase interface between pla and p(3hb-co-4hb) resulted in enhanced chain mobility near interface. the addition of p(3hb-co-4hb) enhanced the cold crystallization of pla in the blends due to the nucleation enhancement of pla caused by the enhanced chain mobility near the phase interface between pla and p(3hb-co-4hb) in the immiscible blends. with the increase in p(3hb-co-4hb) content, the blends showed decreased tensile strength and modulus; however, the elongation at beak was increased significantly, indicating that the inherent brittlement of pla was improved by adding p(3hb-co-4hb). the interesting aspect was that the biodegradability of pla is significantly enhanced after blends preparation. polym. compos., 2012.
