摘要：
The lead-free Na0.5K0.5NbO3-Poly(vinylidene fluoride-trifluoroethylene) (KNN-P(VDF-TrFE)) composite films were prepared by sol-spin coating method. The KNN film was annealed at 700 °C for 3 min with the P(VDF-TrFE) film annealed then at 160 °C for 2 h. The ferroelectric and energy storage properties of composite films were also investigated. The energy storage density of the composite films reached 7.58 J/cm3, and the efficiency was 52%. In addition, the KNN-P(VDF-TrFE) composite films showed weak leakage behavior.
