Ferroelectric Polymers PVDF and P(VDF–TrFE) Films and Their Composites With Either Graphene or Graphene Oxide: Molecular Modeling and Experimental Observations

Boosting Energy Storage of Poly(vinylidene difluoride) Nanocomposite Based Flexible Self-Standing Film with Low Amount of Hydroxylated V2O5

“…PVDF is a polymer that acts as a piezoelectric material and behaves like ferroelectric material. It has very good mechanical properties, excellent thermal properties, and processability, which leads to the applicability of the PVDF in various applications. , The monomer unit of PVDF (CH 2 –CF 2 ) is semicrystal in nature, it has mainly four types of crystalline phases: α, β, γ and δ, out of which α, β and γ are predominant. − H and F have comparable atomic radii due to which PVDF has various crystalline structures. Out of the four phases, α-phase, as the nonpolar phase, is more stable than the other phases.…”

“…Conducting fillers include graphene, carbon black, carbon nanotubes, etc. On the other hand, nonconducting fillers are generally dielectric materials, for example BaTiO 3 , SrTiO 3 , and CaTiO 3 , Pb­(Zr,Ti)­O 3 (PZT). ,,− …”
