Relaxor-ferroelectric and High-k Terpolymers & Inks
Additional CTFE or CFE monomer units, in the well-organized VDF-TrFE chains, improve dipole mobility, thus inducing 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 proportionnal to the applied electric field squared, E²)
- High elastic energy
- High stress
