| Abstract | ||||
| Samples of Ni0.3Zn0.7Fe2O4 and composite films of x% Ni0.3Zn0.7Fe2O4 /PVDF, (x%=5, 10, 15, 20 and 25%) were synthesized by high energy ball milling. The sample milled at 90 hour shows that the intensity peaks of initial oxides reduced during ball milling process and completely disappeared by annealing to 1373 K. There are 2 peaks at (2θ = 18.6 and 27°) corresponding to planes (020) and (021) which are attributed to α- phase of (PVDF) where β-phase of PVDF is characterized by the peaks at (2θ = 20.8°) corresponding to the (110) planes. The phase transformation from the non-polar α-phase to the polar electroactive β-phase of PVDF by increasing NZF content has been investigated by XRD analysis and FTIR spectroscopy. The DC resistivity of the composite samples at room temperature reaches maximum at 5% NZF, above this ratio it begins to decrease. The dielectric constant and dielectric loss were studied at constant frequency. | ||||
