Enhanced dielectric, ferroelectric, energy storage and mechanical energy harvesting performance of ZnO–PVDF composites induced by MWCNTs as an additive third phase

Autor: Samar Kumar Medda, Abhishek Sasmal, Aniket Patra, Shrabanee Sen, Shewli Pratihar

Publikováno v: Soft Matter. 17:8483-8495

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

Nano-ZnO decorated ZnSnO3 as efficient fillers in PVDF matrixes: toward simultaneous enhancement of energy storage density and efficiency and improved energy harvesting activity

Autor: Shrabanee Sen, Samar Kumar Medda, Abhishek Sasmal, P. Sujatha Devi

Publikováno v: Nanoscale. 12:20908-20921

Here, we report the effect of ZnO decoration on ZnSnO3 fillers on the dielectric property, energy storage behaviour and mechanical energy harvesting performance of PVDF matrixes. More enhanced dielectric constant and reduction in dielectric loss were
