Piezotech® FC

P(VDF-TrFE) copolymers, named Piezotech® FC, exhibit high piezoelectric responses over a wide range of temperatures in their poled ferroelectric phase: 

  • High thermal stability of the piezoelectric properties

  • Low power consumption: external power source unnecessary

  • Good mechanical properties

  • High coupling factor

  • Wide frequency range

  • Transparency

  • Chemical resistance

  • High dielectric strength

Compared to PVDF homopolymer, these materials display several advantages: 

  • Upper thermal stability (80 °C for PVDF versus 130°C for Piezotech® FC20)

  • Improved coupling factor (0.15 for PVDF versus 0.3 for P(VDF-TrFE))

  • Printable

  • Enhanced piezoelectric properties (higher d33)

Relaxor-ferroelectric and High-k Terpolymers

Piezotech® RT

Additional CTFE or CFE monomer units are introduced into the well-organized VDF-TrFE chains, which improve dipole mobility, and thus induce unique relaxor ferroelectric properties.

P(VDF-TrFE-CTFE) or P(VDF-TrFE-CFE) are unique relaxor ferroelectric polymers that exhibit high electrostrictive strain and high dielectric constants.

  • High deformation (directly proportional to the applied electric field squared, E²)

  • High elastic energy

  • High stress.
