However, for the moment, it is still a challenge to fabricate dielectric composites combining large electrical breakdown strength and high discharged energy density. Ferroelectric (K0.5Na0.5)NbO3 (KNN) particles are fabricated by solid-state reaction and introduced into poly(vinylidene fluoride) to improve energy storage capability. Particularly, the properties such as dielectric constant (εr), electric displacement, breakdown strength (Eb) and discharged energy density (Udis) are enhanced with the introduction of KNN particles. The composite containing 3 vol% KNN particles exhibits an ultrahigh Udis of 14.70 J·cm−3 at 480 kV·mm−1, which is approximately three times that of pure PVDF of 4.80 J·cm−3 at the applied electric field of 350 kV·mm−1. This research is of critical significance for proposing a convenient and effective way to design high discharged energy storage dielectric composites for future flexible portable capacitors. Keywords: dielectric composite, (K0.5Na0.5)NbO3 particle, breakdown strength, discharged energy density. Volume44, Issue14November 2020Pages 12169-12179 RelatedInformation
