A flexible polymer nanocomposite has been developed via introducing Nd-doped BaTiO_(3)nanoparticles into the poly(vinylidene fluoride).This nanocomposite delivers a discharged energy density up to 12.5 J/cm^(3)under an electric field of 420 kV/mmwith only a small loading of 1 vol.%Nd-BaTiO_(3).High discharged energy density,mechanical flexibility,light weight,ease fabrication and low cost makes it attractive for advanced microelectronics and electrical power systems.Our results demonstrate that ceramics with giant dielectric permittivity as viable fillers for polymer nanocomposite dielectrics with higher energy density.
