(a) Discharged energy density of P(VDF-HFP) at room temperature. (b) The Weibull breakdown field as a function of temperature. The predictions on the electromechanical breakdown strength of P(VDF-HFP) at various temperatures based on the Stark–Garton model and power law model are also presented. Data points are shown here and solid curves are drawn to guide eyes. The error bar with experimental data indicates the standard deviation.
