Summary:Flexible polymer composites with high dielectric constant and breakdown strength thus high energy storage density are highly desired in electrical and electronic technologies. In this study, hybrids of nano Ag particles discretely grown on the surface of BaTiO3 nanofibers (BTnfs) were synthesized and used to fabricate PVDF based nanocomposites. The results demonstrated that the dielectric constant and energy storage density of the composites were largely enhanced. An energy density of 10.25 J/cm3 was obtained for the composite containing only 2.5 vol% hybrids, increased by more than 2 times in comparison with pure PVDF.
