Flexible composite samples were prepared by hot pressing of BiFeO3 powders prepared by
chemical methods with polyvinylidene fluoride (PVDF). Role of PVDF is not only to make the
samples flexible, but also to improve the properties of BiFeO3, primarily to prevent the problems
with high density of leakage currents. Microstructure of composites showed good homogeneity
and uniform thickness of around 50 μm. Dielectric, impedance, ferroelectric and ferromagnetic
properties of composite samples were studied and compared with those of BiFeO3 powders or
ceramic samples. Flexible samples exhibited improved electrical resistivity, which enables them
to withstand significantly higher electric fields and to be weakly polarized. By eliminating the
sintering step, it is possible to retain weak ferromagnetism originating from Fe3O4 nanoparticles
formed during the synthesis in compact samples.
