Poly(vinylidene fluoride)-based macroporous separators for supercapacitors

---

Abstract.
Macroporous polymer separators based on poly(vinylidene fluoride) (PVdF) and several VdF copolymers
were prepared by a phase inversion process using acetone as a solvent. The resulting macroporous
separators were characterized in terms of morphology, swelling behaviour, thermal and mechanical
properties and ionic conductivity. The PVdF separator had a highly porous structure (80%) and exhibited
good mechanical properties. Once filled by a molar solution of tetraethylammonium tetrafluoroborate
(TEABF4) in acetonitrile (AN) it provided enhanced conductivity (18 mS cm−1 at 25 ◦C) compared with
commercial cellulose and CelgardTM separators.
