Abstract

Herein, the designed 3D-BaTiO₃ network in polymer composites results in enhanced permittivity and energy storage density. High permittivities of 200 (ε_eff/ε_m ∼ 55.4) and 34.5 are achieved in the composites with only 30 vol% and 16 vol% 3D-BaTiO₃, respectively. The latter exhibits a discharged energy density that is over 16 times larger than the polymer matrix.
