“…In the field of polymer dielectrics, computational simulation has become a new and effective way to promote the development of this field, and it plays an important role in the performance analysis and rational design of polymer dielectrics. − Wang applied the phase field method to composite dielectrics to explore the relationship between the filler orientation and the macro-dielectric properties, and realized the connection between the microscopic structure and the macroscopical properties . Additionally, the phase field method was adopted by Hong to realize the dynamic simulation of the breakdown process of dielectrics, and the influence of the structure and electrode conditions on the dielectric breakdown was studied .…”

With the development of advanced electronic devices and electric power systems, polymer-based dielectric film capacitors with high energy storage capability have become particularly important. Compared with polymer nanocomposites with widespread attention, all-organic polymers are fundamental and have been proven to be more effective choices in the process of scalable, continuous, and large-scale industrial production, leading to many dielectric and energy storage applications. In the past decade, efforts have intensified in this field with great progress in newly discovered dielectric polymers, fundamental production technologies, and extension toward emerging computational strategies. This review summarizes the recent progress in the field of energy storage based on conventional as well as heat-resistant all-organic polymer materials with the focus on strategies to enhance the dielectric properties and energy storage performances. The key parameters of all-organic polymers, such as dielectric constant, dielectric loss, breakdown strength, energy density, and charge–discharge efficiency, have been thoroughly studied. In addition, the applications of computer-aided calculation including density functional theory, machine learning, and materials genome in rational design and performance prediction of polymer dielectrics are reviewed in detail. Based on a comprehensive understanding of recent developments, guidelines and prospects for the future development of all-organic polymer materials with dielectric and energy storage applications are proposed.

“…[12,22,38] The incorporation of 10 phr MFS and 2 phr graphene in silicone rubber led to an increase in dielectric constant of the composites mainly thanks to the higher dielectric constant of the fillers as well as maybe a slightly local interfacial polarization on the surface of the inclusions. [3,12,39,40] Loading of MFS and MFS/G did not result in any significant alteration of the dielectric loss of the composites. The addition of TiO 2 to the S rubber was resulted in a higher dielectric constant due to significant higher permittivity of TiO 2 (approximately 110) with respect to the silicone rubber (3.1), [41] as well as a significant charge accumulation at the surface boundaries of the TiO 2 particles (interfacial polarization) which can be enhanced by possible moisture absorption by the filler.…”

High‐temperature vulcanized silicone rubber composites are highly desirable as outdoor insulating materials due to their immense thermal and electrical performance. The aim of this work is to study the role of co‐combined fillers (modified fumed silica [MFS], titanium dioxide [TiO2], with graphene [G]) on electrical and thermal properties of silicone rubber (S) composites. The dielectric response of S/MFS_10 phr and S/TiO2_20 composites tailored with 2 phr G was characterized by broadband dielectric spectroscopy. The hybrid filler/composites were found to show higher thermal stability when 2 phr G was added. In addition, a low quantity of G filler was found to slightly increase the AC dielectric breakdown strength of the S/MFS_10 and S/TiO2_20, where an improvement of 3 and 5% was found, respectively. Several steps were observed in the thermal decomposition of the S rubber composites by thermogravimetric analysis‐Fourier‐transform infrared spectroscopy. Our findings revealed great potentials for fabricating hybrid‐filler/silicone rubber composites with enhanced electrical and thermal properties for outdoor insulating applications.
