Abstract

A novel composite material formed by adding high dielectric inorganic ceramic particles and BNNSs interlayer into a sandwich-structured film.

Concurrently enhanced dielectric properties and energy density in poly(vinylidene fluoride)-based core–shell BaTiO3 nanocomposites via constructing a polar and rigid polymer interfacial layer

“…The breakdown strength ( E b ) is another non-negligible argument for obtaining a high-energy-density. A two-parameter Weibull statistic distribution method is used to evaluate the E b of all samples, as shown in eqn (5): 63 where P ( E ) is the cumulative probability of electric failure, E is the experimental breakdown strength, E b is the characteristic breakdown strength at P ( E ) equal to 63.2%, and β is the shape parameter calculated by linear fitting, and β evaluates the data distribution. The E b results of the polymer films are illustrated in Fig.…”

Symmetric Trilayer Dielectric Composites with High Energy Density Using a Low Loading of KNbO3 Nanosheets

“…Figure summarizes the breakdown electric field and the corresponding discharge energy density of several representative PVDF-based nanocomposites with 2D fillers from previous reports. ,,,,− The 0-1-0 trilayer-structured nanocomposite in our work exhibits an impressive U dis of 19.97 J cm –3 at 536 kV mm –1 , which significantly outperforms many previously reported polymer-based nanocomposites with 2D nanofillers.…”

Achieving high breakdown strength and energy density in all-organic sandwich-structured dielectrics by introducing polyacrylate elastomers

“…The U d of the M-15-M lm under 790 kV mm À1 is outstanding compared to that of many previously reported representative multilayer structure composites, as displayed in Fig. 11(a), [14][15][16][17]34,42,48,[57][58][59][60][61][62][63][64] suggesting that the positive-sandwichstructured M-15-M lm has potential to become a widely used dielectric with excellent energy storage properties.…”
