“…To make a more comprehensive comparison of the energy storage properties between inorganic filler/polymer matrix composites and the all-organic composite, relevant studies are shown in Figure . ,− The breakdown strength of the inorganic filler/polymer matrix composites is mostly concentrated below 550 kV mm –1 with a lower energy storage efficiency, as shown in Figure , which is greatly related to the defects generated by the introduction of inorganic fillers. The all-organic composite in this work can effectively avoid the generation of similar defects, achieve a higher breakdown strength, and maintain high efficiency, which makes it have a higher energy storage density although without a higher dielectric constant like inorganic filler/polymer matrix composites.…”

The increasing energy problem and the demand of environmental protection raise higher requirements for the development of clean energy. Dielectric capacitors have attracted lots of attention as a supporting facility of energy storage and conversion for clean energy, but their further development is limited by the low energy storage performance. In this paper, all-organic composite dielectrics were reported, with a poly(methyl methacrylate) (PMMA)/poly(vinylidene fluoride) (PVDF) composite dielectric with different mixing ratios as the matrix and the organic molecular semiconductor with high electron affinity [6,6]-phenyl C61 butyrate acid methyl ester (abbreviated as PCBM) as fillers. The related test results show that with the increase in the doping contents of PCBM, the energy storage density increases obviously. When the doping content of PCBM is 0.9 wt %, the PMMA/PVDF-based organic composite dielectric possesses an optimal breakdown field of 685.67 kV mm–1, accompanying excellent energy storage performances (Ue , ∼21.89 J cm–3; η, ∼70.34%). The PVDF blended with PMMA strategy not only restrains the ferroelectric polarization loss of PVDF but also improves the breakdown strength of the polymer. More importantly, the polarization and breakdown strength of the composites can be synergistically enhanced by filling with PCBM fillers.

Polymer dielectrics-based capacitors are indispensable to the development of increasingly complex, miniaturized and sustainable electronics and electrical systems. However, the current polymer dielectrics are limited by their relatively low discharged energy density, efficiency and poor high-temperature performance. Here, we review the recent advances in the development of high-performance polymer and composite dielectrics for capacitive energy storage applications at both ambient and elevated temperature (≥ 150 °C). We highlight the underlying rationale behind the material development by constructing the relationship between the physical properties of materials and their energy-storage capability. Challenges and future opportunities are discussed at the end of the review.

“…In addition to the polarization from inorganic particles, the altered phase interface also provides strong interfacial polarization. [49] In spite of increased polarization, the breakdown strength of the nanocomposites shows an obvious reduction especially for highly filled films, due to the low breakdown strength of inorganic particles as well as the electric field distortion at the interfaces caused by the incorporation of the foreign phase. [24] The influence of F127 on the D-E loops of nanocomposites was studied.…”

Ceramic/polymer nanocomposites have been extensively explored for dielectric capacitor application due to their high energy storage performance and ease of processing, flexibility, and low cost. However, improving compatibility between inorganic and organic materials is of great significance and has been a long-standing challenge. In this work, the polymer surfactant Pluronic™ F127 was employed to perform surface modification of BaTiO 3 through a facile solution process. The compatibility between BaTiO 3 nanoparticles and P (VDF-HFP) can be remarkably strengthened by the affinity between F127 polymer chains and the organic matrix. Structural defects such as pores, cracks, and agglomeration of inorganic particles were obviously reduced, and interfacial polarization has been significantly enhanced. The discharged energy density U d and charge-discharge efficiency η reach up to 5.0 J/cm 3 and 58.1% under the breakdown strength of 3740 kV/cm for the nanocomposite containing 1 vol% BT@F127. These dielectric properties are clearly better than the nanocomposite using unmodified BT, as well as similar hybrids reported previously.
