Abstract

The effect of high energy electron irradiation is investigated on poly(vinylidene fluoridetrifluoroethylene), P(VDF-TrFE), copolymers in the broad range of irradiation doses and temperature. It was found that after a suitable electron irradiation condition, ferroelectric polymer materials show exceptionally high electrostrictive response (> 4%), high dielectric constant (>60) with low dielectric loss over a broad temperature range. In addition, the material after irradiation exhibits many features resembling those of a relaxor ferroelectric, suggesting that the electron irradiation breaks up the coherent polarization domain in a normal ferroelectric material into micro-polar regions that transform the material into a relaxor ferroelectric. These distinct features make this material very attractive for a broad range of applications. In this paper we will review the experimental results on various characteristics of material properties including the dielectric and electrostrictive strain response induced at different temperatures under different electron irradiation conditions and their relation with structural changes observed by X-ray and DSC.
