摘要：

X-ray diffraction profiles and piezoelectric strain coefficient d31 of 50μm thick polyvinylidene fluoride (PVF2) films, originally containing non-polar Form 2 type crystallites, have been studied after (i) corona poling (ii) uniaxial stretching and (iii) uniaxial stretching and corona poling. The results suggest that piezoelectricity in this material is of dipolar origin. Furthermore a study of the changes in birefringence and small angle light scattering (SALS) patterns have also been made in the present work. The results indicate that the major contribution to the observed orientation on uniaxial stretching originates from the crystalline region of the polymer. © 1979.
