摘要:
采用偏心转子挤出机两步挤出法,制备了聚己二酸/对苯二甲酸丁二酯(PBAT)/热塑性淀粉(TPS)/微晶纤维素(MCC)复合材料,研究了MCC对复合材料的形貌、结晶结构、力学和热性能的影响。并通过组分和加工工艺优化,制备了PBAT/TPS/MCC复合薄膜,研究了薄膜的力学性能和对水汽的阻隔能力。结果表明,经过两步拉伸挤出加工后,MCC在共混物中分散均匀,提升了增容PBAT/TPS共混物的结晶度和热稳定性。同时,PBAT/TPS/MCC复合材料保持了双连续相结构,具有高的弹性模量。这为制备高性能、低成本的生物降解材料提供了新思路。
Abstract:
The poly(butylene adipate-co-terephthalate)/thermoplastic starch/microcrystalline cellulose(PBAT/TPS/MCC) composites were manufactured by double-axis eccentric rotor extruder based on two-step elongational extrusion. The effects of MCC on the morphology,crystalline structure,mechanical performance and thermal property of composites were systematically studied. Furthermore,the PBAT/TPS/MCC film was manufactured by optimizing composition and processing technology,and the mechanical and water vapor barrier performances of film were also investigated. The results indicated that the MCC is uniformly dispersed in the blend after the two-step elongational extrusion process,which enhances the crystallinity and thermal stability of the compatibilized PBAT/TPS blends. Meanwhile,the PBAT/TPS/MCC composites maintaine a bi-continuous phase structure and have a high elastic modulus. This study provides a new idea for preparing the biodegradable materials with high performance and low cost.
