Gaoru Chen,Xuan Wang,Jiaqi Lin,Wenlong Yang,Haidong Li,Yinian Wen,Landi Li,Zhichao Jiang,Qingquan Lei +8 more
TL;DR: In this article, a designed nano-KTN/Ag core/shell structure endows nano-KNN@Ag/PVDF composite films with excellent properties of remarkably enhanced dielectric permittivity, low loss tangent and flexibility.
Journal ArticleDOI
Interfacial Polarity Modulation of KTa0.5Nb0.5O3 Nanoparticles and Its Effect on Dielectric Loss and Breakdown Strength of Poly(vinylidene fluoride) Nanocomposites with High Permittivity
TL;DR: In this paper, the effects of the morphology, interface, and dielectric constant of inorganic fillers on the dielectrics properties of nanocomposites were systemically studied, and it was found that two kinds of KTa 0.5Nb0.5O3 (KTN) nanoparticles, synthesized via solidstate reaction and hydrothermal method respectively, can bring different influences on the structure and electrical performance of the KTN/PVDF composites.
Journal ArticleDOI
Geometrical shape adjustment of KTa0.5Nb0.5O3 nanofillers for tailored dielectric properties of KTa0.5Nb0.5O3/PVDF composite
