Abstract:

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-neelle 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 achieved 75.42% of porosity, and keeps dimensional stability. It is exhibited over-temperature protection function over 160°C.

Key words: poly(vinylidene fluoride), polyacrylonitrile, electrostatic spinning, separator, over-temperature protection, nanofiber
