摘要 通过混炼工艺制备了聚全氟乙丙烯/聚苯硫醚(FEP/PPS)复合材料;研究了PPS用量对复合材料的微观结构、流动性能和力学性能的影响。结果表明:PPS的加入能显著改善FEP/PPS复合体系的流动性能,但FEP/PPS复合体系的拉伸强度却随PPS用量的增加而逐渐降低。FEP/PPS复合体系流动性改善的机理是弥散分布的PPS液相小颗粒为FEP基体提供了较大的剪切变形空间,而复合材料拉伸强度的降低主要来自于两者界面较差的相容性。 The effects of Polyphenylene Sulfide (PPS) addition on the flowing rate, mechanical proper- ties and microstructure of the perfluoro (ethylene-propylene) FEP/PPS composite prepared by physical blending method were studied. The results indicated that the PPS addition in FEP obviously increases the flowing rate of FEP/PPS system compared with the single FEP, however, the tensile strength dropped with increasing PPS. A mechanism was proposed to explain the raise of the flowing rate that the liquid PPS particles offer FEP the large deformation space under the shearing force during the process. The scanning electron microscopy (SEM) observation showed that the weak combination between FEP and PPS surface results in the decrease of the tensile strength of FEP/PPS system.
