The electrical properties of NiFe2O4-PVDF nanocomposite prepared by sol-gel method

Abstract

NiFe2O4 nanocomposite is a soft magnetic material with low saturation coercivity and magnetization but has high electrical resistivity making this material suitable for electric field applications. The purpose of this study was to determine the effect of NiFe2O4 composition on the electrical properties of NiFe2O4-PVDF nanocomposites prepared by the sol-gel method. Nickel Ferrite nanocomposites - polyvinylidene fluoride (NiFe2O4-PVDF) are made using the sol-gel method and then grown using a spin coating device on a glass substrate. NiFe2O4-PVDF nanocomposites are characterized using X-ray diffraction (XRD) which aims to determine the crystal system, whereas to determine the electrical properties of nanocomposite resistivity Four Point Probe are used. Based on the research conducted on the electrical properties of the NiFe2O4-PVDF nanocomposite, the resistivity value of the NiFe2O4- PVDF nanocomposite with variations in the composition of the PVDF used 10:10, 10:20, and 10:30 was 36.66913333 Ohm.m; 55,63242667 Ohm.m; and 20,85797333 (Ohm.m). While the results of the resistivity values of the nanocomposite NiFe2O4-PVDF with variations in the composition of NiFe2O4 used 10:10, 20:10, and 30:10 are 36,69613333 Ohm.m; 12.07853333 Ohm.m; and 9.616773333 (Ohm.m). It can be concluded that the greater the variation in the composition of NiFe2O4 and PVDF, the resistivity value decreases.
