“…into the polymer matrix turns out to be an effective way to improve the dielectric properties. [4][5][6][7][8] In addition, it should be noted that we need not only high permittivity, but also require low dielectric loss and high breakdown strength for composites in the practical application. 9 For example, polypropylene has been the most popular polymer-based dielectric material for many years because of its extremely low dielectric loss ð$ 0:0004Þ and high breakdown strength about 600 MV/m.…”

The influence of thermal treatment on the dielectric properties and energy storage performances of a classical dielectric nanocomposite system (barium titanate/polyvinylidene fluoride PVDF) was discussed systematically. The results demonstrated that the permittivity of thermal treated nanocomposites increased and dielectric loss decreased compared with the untreated system. In addition, the energy density was also greatly improved due to the inclined residual polarization. For example, the energy density of the treated nanocomposite with 50[Formula: see text]vol.% nanofillers was 3.14 times higher than the untreated nanocomposite at 50[Formula: see text]MV/m. Moreover, the charge–discharge efficiency was also promoted from 6.36% to 56.89%. According to the viewpoint of microstructure, the improvement of the dielectric and energy storage properties would be ascribed to the suppression on void defects in the interphase of dielectric nanocomposite by employing the thermal treatment process. Finally, thermal treatment turns out to be a simple and an effective method to improve the dielectric performances and energy storage properties in the dielectric nanocomposites.

“…Previous work found that the electrospun PI nanofibers possessed excellent mechanical strength [13], superior thermal stability [14], and super high toughness [13], which made them excellent candidates as reinforcements [15,16] and the layer-by-layer hot pressing can improve the uniformity and reduce the porosity of polymer-based composites [17][18][19]. Therefore, in this work, we choose high performance electrospun copolyimide (co-PI) nanofibers as reinforcement and high dielectric performance PVDF as matrix to prepare nanofiber reinforced all-organic composites.…”

“…The multilayered structure means the composite is composed of more than three layers. The utilization of multilayer structural materials has emerged as a potential approach for enhancing the breakdown strength [141], with a particular emphasis on the development of high energy storage performance dielectrics. This strategy has proven to be crucial in advancing the exploitation of such materials [77].…”

Dielectric capacitors have garnered significant attention in recent decades for their wide range of uses in contemporary electronic and electrical power systems. The integration of a high breakdown field polymer matrix with various types of fillers in dielectric polymer nanocomposites has attracted significant attention from both academic and commercial sectors. The energy storage performance is influenced by various essential factors, such as the choice of the polymer matrix, the filler type, the filler morphologies, the interfacial engineering, and the composite structure. However, their application is limited by their large amount of filler content, low energy densities, and low-temperature tolerance. Very recently, the utilization of two-dimensional (2D) materials has become prevalent across several disciplines due to their exceptional thermal, electrical, and mechanical characteristics. Compared with zero-dimensional (0D) and one-dimensional (1D) fillers, two-dimensional fillers are more effective in enhancing the dielectric and energy storage properties of polymer-based composites. The present review provides a comprehensive overview of 2D filler-based composites, encompassing a wide range of materials such as ceramics, metal oxides, carbon compounds, MXenes, clays, boron nitride, and others. In a general sense, the incorporation of 2D fillers into polymer nanocomposite dielectrics can result in a significant enhancement in the energy storage capability, even at low filler concentrations. The current challenges and future perspectives are also discussed.
