Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) is a hydrophobic crystalline copolymer with excellent properties such as good thermal stability, high polarity, ionic conductivity, and good solvent resistance. However, their practical applications are greatly hampered by the low energy density (U e) and efficiency (η). The temperature to which the polymer is subjected. Poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP) copolymer is a promising material for the preparation of hydrophobic VMD membrane due to low crystallinity because of the presence of hexafluoropropylene (HFP) monomer in the main polymer chain.
