Abstract

The fluorine-containing polymer composite filled with piezo-ceramics such as PZT-2, PZT-5A, PZT-8 were prepared by a hot pressing method. The electret composites were treated by an electric discharge plasma process, formed by crystallization via electro-thermal treatment, and polarized. The surface charge density and the charge relaxation time of the electret composite were investigated using thermo-stimulated depolarization and their potential differences were defined via a contactless measurement method. According to the obtained experimental results, the stability of the electret charge of a composite based on F42 + PZT-5A is better than a composite based on F3 + PZT-8.
