Abstract :
The bending piezoelectric coefficients β331 have been calculated (~1.5, 8.3, 10.0 μm) for various cases of unstretched and stretched, unpoled and corona poled, films of SAN. For the ABS films the value of β331~2.6 nC/m was obtained for unstretched and unpoled film, and 4.4 nC/m for corona poled films. A linear relation between β331 and d31 for the heat-treated samples indicates that the major contribution to bending piezoelectricity comes from the dipolar polarization
