摘要
为克服现有隔膜材料孔隙率低、耐热性能差的缺点,采用静电纺丝技术,以耐高温性能较好的聚丙烯腈(PAN)和力学性能较好的聚偏氟乙烯(PVDF)为原料,通过多针头、滚筒接收装置成功制备了具有较高孔隙率和热稳定性等优点的PAN/PVDF/PAN层合纳米纤维隔膜材料,并对得到的3种不同厚度比的纳米纤维复合膜结构与性能进行了测试,探究了聚丙烯腈和聚偏氟乙烯不同厚度比例对纳米纤维膜性能的影响,同时对材料的过温保护功能进行了分析。结果表明,制备的复合纳米纤维隔膜具有75.42%的孔隙率,在160℃内能保持尺寸稳定,并且超过160℃具有过温保护功能。
In order to overcome the low porosity and thermal instability of current separator,the polyacrylonitrile（ PAN） with high temperature resistance and polyvinylidene fluoride（ PVDF） with good mechanical properties as raw materials,PAN/PVDF/PAN laminated nanofiber separator with high porous ratio and good thermal stability was fabricated by electrospinning technology equipped with multi-needle and roller receiver device. The morphology and relative properties of PAN/PVDF/PAN laminated nanofiber separators with 3 types of thickness ratio were investigated and analyzed. The resultant separator achieves 75. 42% of porosity,and keeps dimensional stability. It is exhibited over-temperature protection function over 160 ℃.
