摘要：

Infrared spectra of uniaxially drawn beta-poly(vinylidene fluoride) films were recorded under the influence of an electric field. The direction and strength of the applied field were changed in up to thirteen cycles with a maximum field strength of 240 MV m-1. The field-induced changes of the absorbances of the bands at 445 cm-1 (CF2 rocking) and at 510 cm-1 (CF2 bending) were evaluated. Certain amounts of 180-degrees switching and a structure memory effect are discussed to explain the experimental results obtained for repeated repoling processes.
