Significantly enhanced energy storage performance promoted by ultimate sized ferroelectric BaTiO3 fillers in nanocomposite films

PVDF/BT nanocomposite films composed of ultimate sized ferroelectric BaTiO3 nanocrystals are fabricated by spin-coating of the highly dispersed nanocomposite sol. Remarkable energy storage performance and significant high breakdown strength are obtained in the dense and uniform nanocomposite films containing 10-40  vol.% BT.314
