In the present work, we report the enhanced dielectric, ferroelectric, energy storage and energy harvesting performance of a citrate-gel synthesized Bi1−xBaxFeO3 (x = 0, 0.05, 0.10) incorporating poly(vinylidene fluoride) (PVDF) matrix.

Along with enhanced dielectric permittivity and suppressed dielectric loss, PVDF-ZnO@ZnSnO3 films showed simultaneous enhancement in electrical energy storage density and storage efficiency compared to PVDF-ZnSnO3 composites.

Hydroxylation of a BiFeO3 filler improved the dielectric permittivity, energy storage density and mechanical energy harvesting performance along with reduced dielectric loss of its PVDF based composites compared to that of an untreated BiFeO3 filler.

The present work highlights an attempt of fabricating a nanocomposite by addition of multi-walled carbon nanotubes (MWCNT) as third phase into flexible ZnO-Poly(vinylidene fluoride) (ZnO-PVDF) composites. MWCNT played very important...
