Magnetoelectric properties of nickel nanowires-P(VDF–TrFE) composites

Abstract

h i g h l i g h t s A magnetic anisotropy of the ferromagnetic Ni nanowires was observed. The P(VDFeTrFE) glass transition has an influence on the NWs Ni/P(VDFeTrFE) 0.3% vol composite magnetic properties. The NWs Ni/P(VDFeTrFE) composite was polarized to obtain a significant piezoelectric coefficient of 7 pC N À1. The magnetoelectric coefficient reached the high value of 237 V/(m Oe).

Fabrication of Nickel NanoChains/PVDF Nanocomposites and Their Electrical/Magnetic Properties

“…These values are consistent with the NNCs reduced by hydrazine, showing that our system is a good alternative to these strong reducing systems. These values are also in the same order of magnitude as the magnetic properties of the electro‐deposed nickel nanowires …”

Poling influence on the mechanical properties and molecular mobility of highly piezoelectric P(VDF‐TrFE) copolymer

“…Indeed, the combination of polymer mechanical properties (compared to those of the more usual piezoelectric ceramics) and piezoelectric/pyroelectric functionality pave the way to a variety of applications such as flexible sensors and actuators or in the growing field of energy harvesting . Moreover, they are being used as piezoelectric matrixes for multiferroic (magnetoelectric for instance) composites. A recent resurgence of studies on PVDF co‐ and terpolymers probably originates from these prospects of practical applications …”

Coupling Mechanical and Electrical Properties in Spin Crossover Polymer Composites

“…Smaller values of d 33 are generally observed in composites with nonferroelectic loads. [37] This decrease of d 33 may be attributed to the action of depoling field generated by space charges on the particles during poling. Another explanation is a disruption of the connectivity of the polymer matrix related to the existence of particle agglomerates.…”
