From: Enhanced dielectric constant and energy density in a BaTiO3/polymer-matrix composite sponge
Frequency dependencies of a dielectric constant and b dielectric loss (tanδ) of epoxy/BT sponge composites with various BT loadings at room temperature. The inset of b is frequency-dependent imaginary part (ε“) of dielectric constant of epoxy/BT sponge composites with various BT loadings at room temperature. c Dielectric constants at 1 kHz of epoxy/BT composites with various shapes and various theoretical prediction models. d Enhancement of dielectric constant (εr/εm) and e tanδ at 1 kHz in composites of epoxy/BT sponge, epoxy/BT NWs, and epoxy/BT NPs. f Comparison of dielectric constant in polymer-composites in our work and in literatures. Error bars are SEM.
