Abstract
Recently it has been demonstrated that using a high electron energy irradiation, the electro-mechanical properties of polyvinylidene fluoride - trifluoroethylene, P(VDF-TrFE) copolymers can be improved significantly for example; high electric field induced strain (approx. 4.5%) with high elastic energy density, high dielectric constant (approx. 65 with loss less than at 1kHz), high piezoelectric coefficient (approx. 350 pm/V) and high electro-mechanical coupling coefficient (approx. 0.45). It was found, depending on sample processing and electron irradiation conditions these properties can be controlled. In this talk we will present the experimental data on the effect of processing and irradiation conditions on structural and transitional behavior of copolymers. These structural information coupled with the electro-mechanical properties will be presented in order to show the possibilities for further improvement.
