A Mesoscopic Electromechanical Theory of Ferroelectric Films and Ceramics

We present a multi-scale modelling framework to predict the effective electromechanical behavior of ferroelectric ceramics and thin films. This paper specifically focuses on the mesoscopic scale and models the effects of domains and domain switching taking into account intergranular constraints. Starting from the properties of the single crystal and the pre-poling granular texture, the theory p...

Rayleigh type behavior of the Young’s modulus of unpoled ferroelectric ceramics and its dependence on temperature

The dependence on stress of the low frequency Young’s modulus and mechanical losses of unpoled ferroelectric ceramics has been studied as a function of temperature. The Young’s modulus of unpoled Pb(Zr,Ti)O3 ~PZT! showed a Rayleigh type dependence, analogous to the one already described for the longitudinal piezoelectric coefficient. This has been associated to ferroelectric/ ferroelastic domai...

Fatigue crack growth in ferroelectric ceramics below the coercive field

Perovskite-type ferroelectric ceramics have found many applications in actuators, sensors and memories. One critical limitation on their performance is due to electric fatigue, which refers to the deterioration of material properties associated with electric cycling. The degradation of electrical properties in ferroelectrics, which appears in the hysteresis loop in the form of a decrease of rem...

“Telechelic” Ferroelectric Fluoro Terpolymers With High Chemical Reactivity and Large Electromechanical Response at Ambient Temperature

This paper discusses a new family of telechelic ferroelectric polymorphs fluoroterpolymers having OH and COOH terminal groups. The polymer backbone comprises of vinylidene difluoride (VDF), trifluoroethylene (TrFE), and a small amount of chlorinecontaining third monomers. The slightly bulky chlorine atoms serve as the kinks, which alters the chain conformation from all-trans (β-phase) to tttgtt...
