| 摘 要： | 通过冷压烧结的方法制备了聚四氟乙烯/聚苯酯（PTFE/POB）复合材料。采用差示扫描量热法（DSC）研究了PTFE/POB复合材料的非等温结晶行为，并利用Jeziorny法对所得DSC数据进行分析。结果表明，随着冷却速率的增加，结晶峰向低温方向移动，结晶温度范围增大，结晶度下降；Jeziorny方程能够较好地描述PTFE/POB复合材料的非等温结晶动力学；POB有异相成核作用，改善了PTFE的结晶性能，提高了PTFE的结晶速率。

| Abstract: | Polytetrafluoroethylene/polybenzoate (PTFE/POB) composites, in which POB particles filled PTFE matrix, were prepared by cold molding and sintering in the air. The non-isothermal crystallization behavior of PTFE/POB composites was studied by differential scanning calorimetry (DSC), and the Jeziorny equation was used to analyze the non-isothermal crystallization kinetics. As the cooling rate increased, peak temperature shifted to a lower temperature, crystallinity temperature the peak became wider, and crystallinity reduced. The addition of POB increased crystallinity and the crystallization rate of PTFE. |
