Ferroelectric polymer nanocomposites with boron nitride nanosheets exhibit greatly improved energy densities and higher charge–discharge efficiencies.
The development of advanced dielectric materials with high electric energy densities is crucial importance in modern electronics and power systems. Here, a new class multilayer‐structured polymer nanocomposites presented. outer layers the trilayered structure are composed boron nitride nanosheets dispersed poly(vinylidene fluoride) (PVDF) matrix to provide breakdown strength, while PVDF barium strontium titanate nanowires forms central layer offer constant resulting composites. influence...
A broadband and lightweight microwave absorber has attracted soaring research interest because of the increasing demand for electronic reliability defense security. Lightweight ferrites/graphene porous composites with abundant interfaces are potential high-performance absorbers owing to their balanced attenuation ability impedance matching. Herein, we synthesized hierarchical CoFe2O4/reduced graphene oxide (CFO/rGO) nanocomposites a structure via an in situ solvothermal method. The...
Abstract Polymer dielectrics with excellent processability and high breakdown strength ( E b ) enable the development of high‐energy‐density capacitors. Although improvement dielectric constant K polymer has been realized by adding high‐ inorganic fillers contents (>10 vol%), this approach faces significant challenges in scalable film processing. Here, incorporation ultralow ratios (<1 vol%) low‐ Cd 1− x Zn Se y S nanodots into a ferroelectric is reported. The composites exhibit...
Abstract Although the elastocaloric effect was found in natural rubber as early 160 years ago, commercial refrigeration based on polymer elastomers has stagnated owing to their deficient effects and large extension ratios. Herein, we demonstrate that with uniform molecular chain-lengths exhibit enormous through reversible conformational changes. An adiabatic temperature change of −15.3 K an isothermal entropy 145 J kg −1 , obtained from poly(styrene-b-ethylene-co-butylene-b-styrene) near...
Flexible polymer dielectrics for capacitive energy storage that can function well at elevated temperatures are increasingly in demand continuously advancing and miniaturizing electrical devices. However, traditional high-resistance composed of aromatic backbones have a compromised band gap (Eg) hence suffer from low breakdown strength huge loss high temperatures. Here, based on the density functional theory (DFT) calculations, rigid non-coplanar alicyclic segments introduced into polyimide...
A class of multiferroic, three-phase particulate composites Tb–Dy–Fe alloy, lead–zirconate–titanate (PZT), and polymer are investigated, in which a small volume fraction f alloy particles dispersed PZT/polymer mixture. The measured dielectric, piezoelectric, magnetoelectric properties demonstrate that percolation transition occurs at f∼0.12 the composites. When is low (e.g., f&lt;0.07), exhibit piezoelectric increasing response. In critical range 0.07&lt;f&lt;0.12, such piezo-...
Flexible and eco-friendly dielectric materials with high energy density breakdown strength have promising applications in storage devices.
Traditional dielectric polymers are nonbiodegradable and nonrenewable petroleum-derived synthetic ones. Here, we report on flexible 2D nanolayer-structured nanocomposite films which easily fabricated from aqueous NaOH/urea solutions of biodegradable renewable cellulose boron nitride. Cellulose molecules serve as a stabilizer for exfoliated nitride nanosheet (BNNS) provide the nanocomposites with high constant, while BNNS significantly improves their breakdown voltage. 10 wt % in leads to...

Dielectric polymer nanocomposites with ultralow content of nanofillers exhibit remarkable enhancements in dielectric constant and breakdown strength, yielding high discharged energy densities efficiencies.
Regenerated cellulose/BaTiO3 nanocomposite films were fabricated by incorporation of BaTiO3 nanoparticle (BTNP) or nanofiber (BTNF) in regenerated cellulose (RC) via simple blending aqueous NaOH/urea solution. The results showed that a proper addition BTNP BTNF could improve the dielectric constant, breakdown strength, energy density RC and reduce loss simultaneously. Meanwhile, RC-BTNF composites exhibited better mechanical properties than RC-BTNP. Especially, RC-2BTNF composite film with 2...
