In this study, two methods were used to combine poly (m-phenylene isophthalamide) (PMIA) with polyvinylidene fluoride-hexafluoropropylene (PVDF-HFP). The first [email protected] consisted of coaxial electrospinning and the second PMIA/PVDF-HFP was based on simultaneous electrospinning using two solutions. The morphology, mechanical and thermal properties, ionic conductivity and electrochemical stability of the as-obtained composite membranes were all investigated. Compared to properties of commercial Celgard membrane, the composite membranes [email protected] and PMIA/PVDF-HFP effectively combined the advantages of separate PMIA and PVDF-HFP. They exhibited not only excellent thermal stability and mechanical strength but also outstanding electrochemical stability and battery cycle performance. Moreover, [email protected] composite nanofibrous membrane with core (PMIA)-shell (PVDF-HFP) structure showed superior properties than PMIA/PVDF-HFP membrane prepared by simultaneous electrospinning. Hence, it could be used as ideal separator material in lithium-ion batteries.

在这项研究中，使用了两种方法来结合的聚（米-亚苯基间苯二甲酰胺）（PMIA）和聚偏二氟乙烯-六氟丙烯（PVDF-HFP）。第一个[受电子邮件保护]由同轴静电纺丝组成，第二个PMIA / PVDF-HFP基于同时使用两种解决方案的静电纺丝。研究了所得复合膜的形貌，力学和热性能，离子电导率和电化学稳定性。与商业Celgard膜相比，复合膜[电子邮件保护]和PMIA / PVDF-HFP有效地结合了单独的PMIA和PVDF-HFP的优点。它们不仅具有出色的热稳定性和机械强度，而且还具有出色的电化学稳定性和电池循环性能。此外，[电子邮件保护]具有芯（PMIA）-壳（PVDF-HFP）结构的复合纳米纤维膜显示出比通过同时电纺丝制备的PMIA / PVDF-HFP膜优越的性能。因此，它可以用作锂离子电池中的理想隔板材料。
