| 中文摘要 | biosourced poly(lactic acid) (pla) blends with different content of poly(ethylene oxide-b-amide-12) (peba) were prepared by melt compounding. the miscibility, phase structure, crystallization behavior, mechanical properties, and toughening mechanism were investigated. the blend was an immiscible system with the peba domains evenly dispersed in the pla matrix. the peba component suppressed the nonisothermal melt crystallization of pla. with the addition of peba, marked improvement in toughness of pla was achieved. the maximum for elongation at break and impact strength of the blend reached the level of 346% and 60.5 kj/m2, respectively. the phase morphology evolution in the pla/peba blends after tensile and impact tests was investigated, and the corresponding toughening mechanism was discussed. it was found that the pla matrix demonstrates obvious shear yielding in the blend during the tensile and impact tests, which induced energy dissipation and therefore lead to improvement in toughness of the pla/peba blends. polym. compos., 2013.
