recent years due to their enhanced dielectric performance by combining the high permittivity of nanoparticles
and the high electrical breakdown strength of polymer matrix. Herein we present a review of the recent advances
in the modelling of dielectric energy storage and model-based rational design of polymer nanocomposite dielectrics.
The synthesis strategies and dielectric property behaviors of polymer nanocomposite dielectrics are also
discussed. In particular, this review focuses on key strategies and analytical models for substantial improvements
in energy density of composite dielectrics including interfacial design, microstructural engineering and new highdielectric
filler materials. By applying machine learning techniques in conjunction with the analytical models,
new designs have emerged. To demonstrate the practical applications of polymer nanocomposite dielectrics, a
summary is presented of some recent examples of scale-up production of energy storage devices in electrical
vehicles, pulsed weapons systems and power electronics. Finally, challenges and new application opportunities of
polymer nanocomposite dielectrics are discussed. Indexed by:Journal paper Document Code:J Discipline:Engineering First-Level Discipline:Aerospace Science and Technology Document Type:J Volume:74 Issue:1 Page Number:104844 Translation or Not:no Date of Publication:2020-05-16 Included Journals:SCI -
