Piezoelectric Activity and Field-Induced Crystal Structure Transitions in Poled Poly(Vinylidene Fluoride) Films.

Abstract

Unoriented and biaxially oriented phase II poly(vinylidene fluoride ) films were poled at very high fields up to 4 million V/cm at room temperature. Changes in molecular orientation and crystal structure induced by the high-field poling were studied using x-ray and D.S.C. methods. The piezoelectric coefficients d and e together with the dielectric response were determined using a Piezotron Model U (Toyo Seiki, Tokyo, Japan) for the poled films. (Author)
