Abstract For energy‐storage materials, dielectric capacitors exhibit higher power density than fuel cells, Li ion batteries, and super capacitors, giving them potentional for application in hybrid electric vehicles, high‐speed trains, even spaceplanes. However, their low (ESD) has limited commercialization, which therefore fallen behind the other three named systems to some extent. Because of this, a key factor development dielectric/ferroelectric is an increase ESD. Optimizing electrical...
Single-phase homogeneous (Na0.2Bi0.2Ba0.2Sr0.2Ca0.2)TiO3 powder with high configurational entropy was synthesized by using a solid-state method. Calculations of thermodynamic parameters and related experiments indicate that both enthalpy drive the formation stable system. To further research material's performance, we sintered into ceramic, which exhibited relaxation behavior because disorder microscopic composition. In addition, an applied electric field 145 kV/cm produces discharge energy...
Homogeneous (Na0.5Bi0.5)(1–x)BaxTi(1–y)SnyO3 ceramics were densified by a combination of cold isostatic pressing and microwave sintering (CIP&MS strategy), their phase transition ferroelectric properties investigated. X-ray diffraction (XRD) analysis proves that the reaction between Na0.5Bi0.5TiO3 (NBT) BaSnO3 (BSN) was suppressed fast when x < 0.3. The grain size homogeneous ceramic sample about 1 μm, uniform element distribution detected EDS mapping = 0.2 possesses modest dielectric...
Abstract In this study, a high‐entropy perovskite oxide Sr(Zr 0.2 Sn Hf Ti Nb )O 3 (SZSHTN) was first introduced to Na 0.5 Bi TiO (NBT) lead‐free ferroelectric ceramics boost both the high‐temperature dielectric stability and energy storage performance. Excellent comprehensive performance simultaneously obtained in 0.8NBT–0.2SZSHTN ceramic with high ε ′ value (> 2000), wide ′‐temperature stable range (TCC < 5%, 52.4–362°C), low tan δ (<0.01, 90–341°C) ( W rec = 3.52 J/cm , η varies...
The mechanical durability of superhydrophobic surfaces is significance for their practical applications. However, few reports about coating on certain substrates took into consideration both the stability and adhesion between substrate. Herein, we put forward a facile efficient strategy to construct robust coatings by simply spray-coating composite suspension SiO2 nanoparticles, polydimethylsiloxane (PDMS), epoxy resin (EP) pretreated with an EP base-coating. as-obtained exhibited excellent...
(1 − x )KNN– BCZT-based transparent ceramics with a W rec of 7.83 J cm −3 and an η 81.02% were obtained. High polarization boundaries conductive mechanism transition revealed to be the main reasons for such good performances.
