Summary: A sandwich-structured ferroelectric polymer nanocomposite with high energy density is fabricated by incorporating ultra-small metal particles. The nanocomposite exhibits suppressed leakage current density and superior breakdown strength due to the Coulomb-blockade effect of the metal particles. Pt nanoparticles with high work function are found to be more effective in improving the capacitive performance of the polymer. Furthermore, larger metal particles within the suitable size range show better capacitive performance.

Summary: To improve the energy storage density of capacitors, the ferroelectric phase poly(vinylidene fluoride) (PVDF) is introduced as a modifier. Blending PVDF-doped PMMA composites enhances the polarization strength but sacrifices the breakdown strength due to the presence of defects. To address this issue, a double-layer structure is designed with controlled interfacial bonding achieved through hot pressing. This work successfully achieves high discharge energy density and maintains energy efficiency in PMMA and PVDF composite films.

Summary: A lead-free, simple composition of Ba(Zr,Ti)O-3 has been found to exhibit a pseudo-linear, ultra-slim polarization-electric field hysteresis loop, with a high energy efficiency of up to 90%. This is attributed to the presence of self-assembled, bimodal polymorphic nanodomains, which reduce the remnant polarization and delay polarization saturation. The strain engineering of these nanodomain structures provides a promising alternative to chemical compositional design for optimizing dielectric thin films.

Ultimately, the 0.65BNT-0.35STT ceramic exhibited a large W-rec of 3.3 J/cm(3) and a high eta of 90.4% under 230 kV/cm, demonstrating remarkable potential in pulse power systems.

Summary: In recent years, there has been an increasing demand for high temperature-resistant dielectrics due to the growing need for power supply in harsh environments. However, polymer-based composites with high glass-transition-temperature polymers face challenges in achieving homogeneous dispersion of fillers. This study focuses on the design and preparation of poly-etherimide (PEI)-based nanocomposites filled with modified BT nanoparticles. The nanocomposites, mBT/PEI, exhibit improved dielectric and energy storage performance, with a maximum energy density of 4.2 J cm-3 at 2 vol%, which is 31% higher than that of the nanocomposite BT/PEI without surface modification.

Summary: In this work, a molecular engineering strategy is proposed to regulate the conduction of polymer dielectrics at elevated temperatures by bonding NH2-POSS with PI. The NH2-POSS with a wide-bandgap increases the energy levels of the PI and induces the formation of deep traps in the hybrid films, effectively restraining carrier transport. The NH2-POSS terminated PI film exhibits high discharged energy density, gravimetric energy density, charge-discharge efficiency, cyclability, and power density at 200 degrees C, making it a promising candidate for high-temperature high-energy-density capacitors.

Summary: This paper presents a data-driven approach to design and optimize acoustic metamaterials with three-phase materials for highly tunable wave transmission. The use of trigonometric series function enables the representation of arbitrary shapes with symmetry, allowing for a large sub-wavelength bandgap. An algorithm called 'decoupled gradient descent (DGD)' is proposed to search for the optimal design and determine the most effective shape features to tune the wave transmission. The study demonstrates both passive tunability through overlapping bandgaps and active tunability through surface deformation.
