A Study of the Nature and Origins of Pyroelectricity and Piezoelectricity in Polyvinylidenefluoride and Its Co-Polymers.

Abstract

The results of these experiments indicate that at least a large part of the polarization in PVF2 after poling is due to dipole orientation in the crystalline regions. There is ample evidence to show that crystallites are aligned by the poling field and remain in or close to this new angular position when the field is removed. Ageing experiments indicate that they do not return to their original positions even after annealing at high temperature.
