Nano-KTN@Ag/PVDF composite films with high permittivity and low dielectric loss by introduction of designed KTN/Ag core/shell nanoparticles
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
K0.5Na0.5NbO3-SrTiO3/PVDF Polymer Composite Film with Low Remnant Polarization and High Discharge Energy Storage Density
TL;DR: The results demonstrated that combing ferroelectric- paraelectric particles with polymers might be a key method for composites with excellent dielectric permittivity, high energy storage density, and energy efficiency.
Journal ArticleDOI
Structure and mechanical properties of the hybrid films of well dispersed SiO2 nanoparticle in polyimide (PI/SiO2) prepared by sol–gel process
Jiaqi Lin,Ying Liu,Wenlong Yang,Zhibin Xie,Panpan Zhang,Xiaokang Li,Hui Lin,Gaoru Chen,Qingquan Lei +8 more
TL;DR: In this article, the hybrid films of well dispersed SiO2 nanoparticle in polyimide (PI/SiO2) were prepared through the sol-gel processing, and the results indicated that the chemical interaction between the two phases resulted in the formation of well-dispersed nanoparticles (20-30nm) in the PI matrix, and superior thermal stability of hybrid films.
Journal ArticleDOI
Geometrical shape adjustment of KTa0.5Nb0.5O3 nanofillers for tailored dielectric properties of KTa0.5Nb0.5O3/PVDF composite
Gaoru Chen,Wenlong Yang,Jiaqi Lin,Xuan Wang,Dongping Li,Yu Wang,Mengfan Liang,Weimin Ding,Haidong Li,Qingquan Lei +9 more
TL;DR: In this paper, rational design and precise control for the structure and shape of nanofillers are effective for achieving the desired permittivity and breakdown strength for high energy densities of polymer nanocomposites.
