Polyvinylidene fluoride (PVDF)

PVDF (Polyvinylidene fluoride) is a family of semi-crystalline fluoropolymers. They possess the characteristic stability of fluoropolymers especially when exposed to harsh thermal, chemical and UV environments.

This polymer has two important properties. Firstly, the polymer's polymorphism, and secondly its piezoelectric properties (when crystals generate electrical energy when mechanical stress is applied). It is the later which makes this polymer ideal for tactile sensor arrays, low cost strain gauges and lightweight audio transducers.

  • History

    • 1969: Dr. Heiji Kawai discovered the piezoelectric properties of PVDF.
    • 1981: Furakawa and Johnson confirmed PVDF’s piezoelectric nature and identified the Curie point of 103ºC. (The Curie point is the temperature above which the piezoelectric effect breaks down.)
