Excellent energy storage performance in polymer composites with insulating and polarized two-dimensional fillers

Superior capacitive performance achieved in wide HOMO–LUMO gap cyanoethyl cellulose nanocomposites via forming a built-in electric field

“…Based on organic/inorganic composites, the lower defect content favors the stability, and the excellent stability performance of 0.2 wt% BFO@AO/CRC films confirmed its outstanding compatibility between the filler with the polymer, as shown in Fig. 4d 7,37–43 A considerable power density and ideal charge/discharge rates allow electrostatic capacitors to be used in electromagnetic artillery, high-voltage cables, and other applications. Fast charge–discharge tests of CRC and its nanocomposites were performed at 180 MV m −1 DC voltage, as shown in Fig.…”

Remarkably enhancing dielectric permittivity and suppressing loss of PVDF via incorporating metal nanoparticles decorated glass fibers

“…Subsequently, the calcined Au@GF frameworks were dip-coated with the above PVDF slurry under vacuum for 10 min, and then hung in a hot oven for 4 h at 100 • C to completely remove the solvent (DMF). The composites were heated to 200 • C for a few minutes and then quenched in ice-cold water immediately, which is beneficial for maintaining the β phase of PVDF [6,16,20,21]. In comparison, the above pure PVDF solution was uniformly casted onto a clean quartz plate and pure PVDF films were prepared using the same drying and quenching steps.…”

“…many advanced power and electronic applications, including energy storage capacitors, 5G base stations and transmission cables [1][2][3][4]. Polymer dielectrics have been found to be widely attractive in recent years because of their selfhealing capability, high flexibility, low dielectric loss and high voltage resistance [5][6][7][8][9]. Unfortunately, compared with inorganic dielectrics, polymer dielectrics suffer relatively low permittivity (<10 at 1 kHz) due to the inherent low polarization of carbon-hydrogen covalent bonds, which greatly limit their practical applications [7].…”

The strength of particulate polymer composite: A new insight on crystallinity and structural morphology

“…Their exceptional properties, including their lightweight, acceptable thermal and electrical properties, high strength, and ease of manufacture, have made them an important material in engineering. [1][2][3][4][5][6][7][8][9] The addition of fillers provides the overall properties of the composite with new or improved properties. Inorganic clay minerals, [10][11][12] carbon nanotubes, [13][14][15] and graphene [16][17][18] are some examples of fillers that have a high aspect ratio.…”
