Preparation of high piezoelectric and flexible polyvinylidene fluoride nanofibers via lead zirconium titanate doping

Magnetoelectric (ME) coupling in layered structures of magnetostrictive and piezoelectric phases are mediated by mechanical deformation and depends strongly on the interface conditions. Ni -lead zirconium titanate- Ni trilayers with neither electrodes nor bonding layers have been derived by electroless deposition. The structure of the electroless deposited Ni layer was characterized by X-ray diffraction. The cross-section of the Ni/PZT layers was investigated using scanning electron microscopy. The value of ME voltage coefficient (αE,31) increases as the interface roughness increases. The maximum of αE,31 for the Ni/PZT/Ni trilayers polarized after electroless deposition is higher than that for the Ni/PZT/Ni trilayers polarized before electroless deposition. It is essential to optimize the interface and the polarization to obtain higher ME voltage coefficient.

Scanning Electron

Magnetoelectric (ME) nickel and lead zirconium titanate multi-layers with neither electrodes nor bonding layers was developed by electroless deposition. Scanning electron microscopy reveals that the Ni layer is in direct contact with the PZT layer without inter-layer not only in Ni /PZT/ Ni trilayer but also in Ni /PZT/ Ni /PZT/ Ni multi-layer. The in-plane parallel magnetostriction has been measured for electroless deposited Ni . The saturation magnetostriction is 32.6 × 10-6. When the total thickness of multi-layers is the same, the ME voltage coefficient α E,31 decreases with increasing the stacking periodicity. On condition that the thickness of each layer is the same, the ME voltage coefficient V E,31 of the Ni /PZT/ Ni /PZT/ Ni multi-layer is nearly twice higher than that of the Ni /PZT/ Ni tri-layer at the resonance frequency, which provides a new choice to obtain higher ME voltage coefficient.
