Original Research


Dielectric polymer-based nanocomposites with high dielectric constant and energy density have attracted extensive attention in modern electronic and electrical applications. Core-satellite BaTiO3-CoFe2O4 (BT-CF) structures with a BT core of ~ 100 nm and CF satellites (~ 28 nm) on the surface of the BT particle were prepared. The dielectric properties and energy storage density of PVDF nanocomposites were enhanced by BT-CF heterostructures at a small loading of CF nanoparticles. Compared to the general adopted BT/PVDF composites, the dielectric constant can be effectively improved with no additional loss by introducing a small amount of CF nanoparticles to the BT/PVDF composite. Moreover, the energy density and efficiency of the BT/PVDF nanocomposites were also improved by the small loading of CF. The discharged energy density of the BT-CF/PVDF nanocomposites with 7 wt.% CF nanoparticles showed that the maximal energy density value is 5.60 J/cm3 at the electric field of 263 kV/mm. The results showed that the small amount of CF nanoparticles has beneficial effects on enhancing the dielectric constant and energy storage of the BT/PVDF nanocomposites.
