Résumé
Nanocomposite films composed of nanoparticles Fe3O4embedded in copolymers of vinylidene fluorideand trifluoroethylene P(VDF-TrFE) (70/30) have been elaborated. The effect of Fe3O4content on thecristallinity ratio, dielectric and magnetoelectric properties of the nano-piezo-composites was studiedand discussed. Dielectric characterization showed an increase of the permittivity and a decrease of theresistivity with the increasing ratio of nanofillers. Thermal analysis revealed a decrease of the cristallinityof the composite. Poling process was found to be difficult for Fe3O4contents higher than 1%, because ofthe low breakdown fields and diminished resistivity with increasing Fe3O4content. As a consequence,magnetoelectricmeasurementswereconductedonlyonnanocompositeswithFe3O4contentslowerthan0.5% in the case of poled samples. The optimal value of the first order magnetoelectric (ME) coefficient ̨pwas obtained for a nanoparticles content of 0.3% wt.
