The Effect of Plasticizer on the Piezoelectric Properties of Unoriented Polyvinylidene Fluoride Films.

Abstract

The effect of plasticizer content on the piezoelectric response of unoriented polyvinylidene fluoride was measured. The plasticizer was added both before and after poling. In both cases the piezoelectric strain constant d31 increased appreciably with increasing plasticizer content. When the plasticizer was added before poling, the piezoelectric stress constant e31 also increased with plasticizer content. The reverse effect was observed for e31 if the plasticizer was added after poling (probably due to film depolarization). These changes in d31 and e31 are related to the bulk mechanical and dielectric properties of plasticized films. (Author)
