Abstract

As me polarization in a vinylidene fluoride/trifluoroethylene copolymer is reversed repeatedly, it shows the fatigue phenomena: the reduction of remanent polarization (P_r), the increase in switching time (τ_s). The electrode area may also decreased by burning and eventually breakdown occurs. Such characteristics are shown to depend on the species of electrodes, thickness, amplitude of the applied electric field and the repeating cycle of the polarization reversal. P_r increases up to repeating cycles of 10⁴ and then decreases linearly to the logarithm of the cycles. These phenomena are suppressed if higher repeating frequency or lower voltage amplitude are adopted.
