Ultrahigh Energy Density of Polymer Nanocomposites Containing BaTiO₃@TiO₂ Nanofibers by Atomic‐Scale Interface Engineering

Abstract

Atomic-scale interface engineering in BaTiO3@TO2 nanofibers (TiO2 nano­fibers embedded with BaTiO3 nano­particles) leads to concurrent enhancement of electric displacement and breakdown strength in poly(vinylidene fluoride) (PVDF)-based nanocomposites. An ultrahigh energy density of ≈20 J cm–3 is achieved with only 3 vol% nanofibers, which is by far the highest discharged energy density of PVDF-based nanocomposites.
