homologues in the near future. In this work, poly(propylene 2,5-furandicarboxylate) (PPF) nanocomposites with graphene nanoplatelets were prepared via the in-situ melt polycondensation method. The chemical structure of the resulting polymers was confirmed by 1H-NMR spectroscopy. Thermal stability, decomposition kinetics and the decomposition mechanism of the PPF nanocomposites were studied in detail
生物基聚酯是一类新型材料,有望在不久的将来取代其基于化石的同系物。在这项工作中,通过原位熔融缩聚法制备了具有石墨烯纳米片的聚(2,5-呋喃二甲酸丙二酯)(PPF)纳米复合材料。所得聚合物的化学结构通过1 H-NMR光谱确认。详细研究了PPF纳米复合材料的热稳定性,分解动力学和分解机理。根据热重分析结果,石墨烯纳米薄片在0.5、1.0和2.5 wt。%的水平下不会影响PPF的热稳定性,但会导致活化能值略有增加。
