PVDF-based multiferroic

Multiferroic materials-able to show a good magnetoelectric effect-have been subjected to increasing research in recent years because of the possibility to combine electric and magnetic properties at the same time in the same material. Two kinds of multiferroic materials exist, single-phase and composite materials. The first present some drawbacks that moved research toward the second ones. The fabrication of composite multiferroics includes the possibility of tailoring the properties using two different compounds, one being ferromagnetic and the other being ferroelectric and then combining them. Ferroelectric polymers such as PVDF and its copolymers can be used as starting materials for these composites. Their ability to self-assemble can allow direct control over the interaction of these polymers with magnetic nanoparticles that can be dispersed inside the polymer. The interaction between the ferroelectric block and the ferromagnetic nanoparticles determines the quality of the magnetoelectric effect.
