Opis

Opis ogólny

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.

Zastosowanie

Owing to its high polarity, wettability by organic solvents, and relatively high ionic conductivity, PVDF-HFP is widely used as a polymer matrix to prepare gel polymer electrolytes for energy storage applications. For example, it can be used to enhance the performance of flexible solid-state supercapacitors.

It can be used to prepare superhydrophobic polymer nanocomposites. For example, PVDF-HFP- SiO₂ composite can be used to enhance the thermochromism in regioregular poly(3-hexylthiophene), P3HT.

It can also be used to prepare lead-free piezoelectric flexible polymer composites for nanogenerators. PVDF-HFP can be preferred over other polymer matrices because of its higher solubility, greater free volume, and better mechanical strength.

Wire and cable coatings, flexible and corrosion-resistant tubing, and liners for pipes and tanks.

Cechy i korzyści

Excellent thermal stability, chemical and abrasion resistance, impervious to UV degradation, self-extinguishing and retains properties on aging. Improved flexibility at subzero temperatures, stress crack resistance and elongation to break over poly(vinylidene fluoride).

Postać fizyczna

Crystalline, thermoplastic copolymer.
