“…The results demonstrated that the organic fillers exhibited better compatibility with PVDF than the inorganic fillers and further helped to suppress the breakdown damage at the interface. Wen et al 28 introduced poly(acrylonitrile butadiene styrene) (ABS) into PVDF. The composites possessed excellent energy storage (U d maintained 11.42 J cm À3 at 100 1C) due to the intermolecular interaction between ABS and PVDF (CRNÁ Á ÁC-H) and the introduction of deeps traps.…”

High losses and low efficiency have been the main defects limiting poly(vinylidene fluoride) (PVDF) as an energy storage film capacitor material. Herein, the linear methyl methacrylate-co-glycidyl methacrylate (MG) copolymer was prepared to improve the dielectric and energy storage performance of PVDF. FTIR spectroscopy and XRD results showed that the introduction of MG induced the crystal phase transformation of PVDF. Polarized optical microscopy and DSC tests proved the smaller crystal size and lower crystallinity of PVDF in the composites. The introduction of MG decreased the permittivity of PVDF and suppressed dielectric and conductive losses. The composites showed higher breakdown strength, which increased from 300 MV/m for PVDF to 540 MV/m for the PVDF/MG-40% composite. Despite the weak polarity of MG, the complementary breakdown strength endowed excellent discharge energy density and efficiency for the PVDF/MG composites. The discharge energy density increased from 3.75 J/cm 3 for PVDF to 9.2 J/cm 3 for the PVDF/MG-40% composite. Meanwhile, the PVDF/MG-40% composite still maintained a high efficiency of 84% even at a 540 MV/m electric field. This research provides a feasible design idea for all-organic composite membranes. More importantly, the reactive activity of epoxy groups on the MG copolymer can be utilized for later performance optimization of PVDF/MG dielectric membrane through regulation strategies.

The breakthrough of energy storage technology will enable energy distribution and adaptation across space‐time, which is revolutionary for the generation of energy. Optimizing the energy storage performance of polymer dielectrics remains challenging via the physical process of electrical breakdown in solid dielectrics is hard to be intuitively obtained. In this review article, the application of computational simulation technologies is summarized in energy‐storage polymer dielectrics and the effect of control variables and design structures on the material properties with an emphasis on dielectric breakdown and energy storage performance are highlighted. The prediction and evaluation of material properties by combining various data analysis methods are reviewed. Finally, the outlook and challenges are discussed based on their current developments. This article covers not only an overview of the state‐of‐the‐art advances of breakdown modeling in energy‐storage polymer dielectrics but also the prospects that provide a new knob to synthesize high energy‐storage polymer dielectrics via computational simulation and a new research paradigm.
