Abstract
A second order dielectric constant which represents nonlinear properties of material depends remarkably on the remanent polarization of the material. This paper describes the polarization dependence of second order dielectric constants in ferroelectric copolymers of vinylidene fluoride and trifluoroethylene. The remanent polarization of samples is controlled by means of an electrically or thermally stimulating procedure, both of which depolarize partially the fully polarized sample. The second order dielectric constants of the two sorts of samples made by these two methods show different types of dependence on the remanent polarization. This is interpreted by the phenomenological theory which predicts the thermodynamical order of a ferroelectric phase transition.
