聚2,5-呋喃二甲酸乙二醇酯/聚丁二酸丁二醇酯共混物的制备与表征
摘要:
通过熔融共混制备了聚2,5-呋喃二甲酸乙二醇酯(PEF)/聚丁二酸丁二醇酯(PBS)共混物,探究了制备PEF/PBS共混物的影响因素,考察了共混温度、共混时间、螺杆转速、共混比例对PEF/PBS共混物力学性能的影响因素,并用示差扫描量热仪、热失重、扫描电子显微镜等技术手段对其热性能和相容性进行了表征。结果表明,当PBS的含量为15%、共混温度为230℃,共混时间为90 s、螺杆转速为150 r/min时,为最佳共混制备条件,此时相容性最好,热性能良好,冲击强度和拉伸强度最大,冲击强度相对纯PEF提高了6倍,拉伸强度提高了近20%,从而大幅提高了PEF的冲击强度,有效地增强了PEF的抗冲击韧性。这些工作为这一生物基聚酯材料的应用提供了可能。

Preparation and Characterization of Poly (ethylene2,5-furandicarboxylate)/Poly (butylene succinate) Blends
Abstract:
Poly (ethylene 2,5-furandicarboxylate)(PEF)/poly (butylene succinate)(PBS) blends were obtained via melt blending,and the factors,such as the blending temperature,blending time,the screw speed and blending ratio on mechanical properties of PEF/PBS blends were studied in details.Their compatibility,thermal property,and mechanical property were investigated by scanning electron microscopy,differential scanning calorimetry,thermogravimetric analysis,and tensile testing and impact testing.When the content of PBS is 15%,the optimal blending processing conditions are mixing the blends at 230℃ for 90 s under the screw rotation speed of 150 r/min.Under the optimal conditions,the compatibility and thermal performance are good,the impact strength and tensile strength are the largest.Compared to PEF,the impact strength and the tensile strength of the blend increase 6 times and approximate 20%,respectively.The results in this work provide a new possibility for the application of biobased polymers.
