摘要：
The effect of the relative content of alpha- and beta-crystalline forms on the piezoelectric properties of PVDF has been investigated in extruded and casting films. The results are discussed in terms of the dependence of e31 on the relative intensity of the X-ray (110+200 to 020) diffraction lines. The relations obtained are compared to those previously reported. The changes in the crystalline form content were found to be due to the treatment commonly applied in the piezopolymer formation process.
