![]() ![]() The considerable progress witnessed in energy storage performance is further justified by a finite element simulation that reveals the positive effects of the core–shell particles on polarization and energy density distribution across the interfaces. A comparative study on three core–shell designs (BaTiO 2O 3, BaTiO BaTiO 2) revealed the favorable role of higher thermal conductivity (321 W m −1 K −1 for AlN and 25 W m −1 K −1 for Al 2O 3) in enhancing the dielectric strength of the PEI film as well as inferior lossy behavior induced by the TiO 2 shell under high electric fields. For the first time, the dilute nanofillers fabricated with the ALD technique incorporated in a polyetherimide film simultaneously enhanced the dielectric strength and dielectric constant of the composites. ![]() Three different shell materials feature different thermal conductivity and dielectric permittivity. In this work, the authors introduce an uncustomary atomic layer deposition (ALD) method to construct the core–shell heterostructure of BaTiO 3 nanoparticles. Novel concepts are highly anticipated to enhance dielectric strength and energy density while suppressing dielectric loss and the mechanism behind it. For twenty years, researchers have investigated nanodielectric composites to advance their dielectric properties toward practical applications in capacitors and electrical insulation. ![]()
