6 天之前 · PVDF-HFP’s thermal stability and mechanical performance depend on the ratio of hexafluoropropylene to polyvinylidene fluoride. HFP disrupts the crystalline structure, lowering the melting point compared to pure PVDF while increasing flexibility. The melting transition typically ranges between 140°C and 170°C, depending on composition.

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.
