Flexible electrostatic capacitors are potentially applicable in modern electrical and electric power systems. In this study, flexible nanocomposites containing newly structured one-dimensional (1D) BaTiO3@Al2O3 nanofibers (BT@AO NFs) the ferroelectric polymer poly(vinylidene fluoride) (PVDF) matrix were prepared systematically studied. The 1D BT@AO NFs, where BaTiO3 nanoparticles (BT NPs) embedded homogeneously dispersed into AO nanofibers, successfully synthesized via an improved...

Abstract Dielectric capacitors have become a key enabling technology for electronics and electrical systems. Although great strides been made in the development of ferroelectric ceramic thin films capacitors, much less attention has given to preventing polarization fatigue, while improving energy density, ferroelectrics.

The layered composite exhibits much higher constant than current high-temperature composites, while simultaneously retaining low loss at...
One-dimensional (1D) materials as fillers introduced into polymer matrixes have shown great potential in achieving high energy storage capacity because of their large dipole moments. In this article, 1D lead-free 0.5(Ba0.7Ca0.3)TiO3–0.5Ba(Zr0.2Ti0.8)O3 nanofibers (BCZT NFs) were prepared via electrospinning, and formation mechanism was systematically studied. Polypropylene acyl tetraethylene pentamine (PATP) grafted the surface BCZT NFs embedded matrixes, which effectively improved...
Electrostatic capacitors have been applied into high-power-density pulsed power systems comprising moderate energy density and ultrafast charging/discharging in the order of magnitude with a few milliseconds.
