摘要

采用熔融共混制备了聚对苯二甲酸-己二酸丁二酯(poly(butylene adipate-

-terephthalate)，PBAT)与聚3-羟基丁酸酯4-羟基丁酸酯(poly(3-hydroxybutyrate

-co

-4-hydroxybutyrate)，P34HB)的共混材料。研究了P34HB含量(0 wt%

5 wt%、10 wt%、15 wt%、20 wt%)对共混材料熔体流动性能、力学性能、热性能和界面微观形貌的影响，及其PBAT/P34HB吹塑薄膜的力学性能和氧气阻隔性能。结果表明，P34HB的加入降低了材料的熔体黏度，提高了材料的流动性以及薄膜的直角撕裂性能、穿刺性能和氧气阻隔性能。当P34HB含量为5 wt%时，共混材料综合性能最佳，两相相容性良好，共混材料和吹塑薄膜均具有优异的力学性能，薄膜的拉伸性能和穿刺强度最高，是性能优异的包装和农膜材料。

Abstract

The blends of poly(butylene adipate-

-terephthalate) (PBAT)/poly(3-hydroxybutyrate-

-4-hydroxybutyrate) (P34HB) were prepared by melt-compounding. The effects of P34HB content (0 wt%

5 wt%

10 wt%

15 wt%

20 wt%) on the melt flowability

tensile properties

thermal behavior and interfacial morphology of the blends were investigated. The mechanical properties and barrier properties of the blown films were also studied. The results indicated that the incorporation of P34HB increased the melt flowability of PBAT

improved the right-angle tear strength

puncture strength and oxygen barrier property of blown films. When the weight content of P34HB is 5 wt%

the blend exhibited the highest comprehensive performance

PBAT and P34HB showed good compatibility

the blend displayed excellent mechanical properties for both injection samples and blown films

and the film demonstrated the highest tensile and puncture strength

showing promising application prospects for package and agriculture film.
