Nanostructured materials are central to the evolution of future electronics and information technologies. Ferroelectrics have already been established as a dominant branch in the electronics sector because of their diverse application range such as ferroelectric memories, ferroelectric tunnel junctions, etc. The on-going dimensional downscaling of materials to allow packing of increased numbers of components onto integrated circuits provides the momentum for the evolution of nanostructured ferroelectric materials and devices. Nanoscaling of ferroelectric materials can result in a modification of their functionality, such as phase transition temperature or Curie temperature (TC), domain dynamics, dielectric constant, coercive field, spontaneous polarisation and piezoelectric response. Furthermore, nanoscaling can be used to form high density arrays of monodomain ferroelectric nanostructures, which is desirable for the miniaturisation of memory devices. This review article highlights some research breakthroughs in the fabrication, characterisation and applications of nanoscale ferroelectric materials over the last decade, with priority given to novel synthetic strategies

“…The incorporation of ZnO nanorods would induce large interfacial areas in composites which may result in a higher degree of interfacial polarization. On the other hand, the polarization and dielectric properties of the PVDF based ferroelectric polymers originate from their crystalline domain and the β phase exhibits piezoelectric and pyroelectric properties [21][22][23][24][25] , so it is reasonable to deduce that the formation of β phase do contribute to the enhancement of dielectric constant. And the decrease rate of the dielectric constant here is not remarkable.…”

Abstract.Zinc oxide (ZnO) nanorods were synthesized using a modified wet chemical method. Poly(vinylidene fluoride-co-hexafluoropropylene), P(VDF-HFP), nanocomposites with different ZnO nanorods loadings were prepared via a solution blend route. Field emission scanning electron microscopic (FESEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR) were used to investigate the structure and morphology of the nanocomposites. XRD and FT-IR data indicate that the incorporation of ZnO nanorods promote the crystalline structure transformation of P(VDF-HFP). As the content of ZnO nanorods increases, the β phase structure increases while the α phase decreases. In addition, the dielectric properties of the P(VDF-HFP) and its composites were systematically studied.

“…However, from a practical point of view, the energy density is determined by the processing method and quality of the film as failure is often driven by flaws. The current trend in searching for high energy density capacitors is to use polymer-matrix composites with ferroelectric fillers, combining high dielectric permittivity of the ceramic with high breakdown strength of the polymer [4][5][6][7]. Nanowires of Ba 0.2 Sr 0.8 O 3 nanocomposites have been reported to have an energy storage density as high as 14.86 J/cm 3 at 450 MV/m [8].…”

Enhanced Energy Storage with Polar Vortices in Ferroelectric Nanocomposites

Nanocomposites of ferroelectric ceramic filler and polymer matrix show considerable promise as high energy storage dielectric capacitors. However, the influence of microstructure of the ferroelectric filler on the electric energy storage performance in the nanocomposite has not been quantitatively studied, yet it is a key element in understanding the methods employed to improve the performance of capacitors. We demonstrate an innovative strategy to enhance the energy storage density with topological vortex structures in nanocomposites. Using three dimensional phase field calculations, we show that multi-vortex structures can exist in ferroelectric nanowires without charge defects or free charges at the interface between the filler and matrix. The switching behavior of the topological structure (vortex and anti-vortex pair) under external electric field is calculated in nanocylinder wires. The small remnant polarization and very narrow hysteresis loop due to the vortex structure in the nanocomposites can lead to a large enhancement of energy density, as high as 5 J/cm 3 compared to 1-2 J/cm 3 for commercial capacitors, and high energy storage efficiency (over 95%) at a relatively low electric field of 140 MV/m.
