Effect of Co-Precipitation on the Physico-Mechanical and Dielectric Properties of Nickel Ferrite Embedded Natural Rubber Composites
Spinel structured nickel ferrite has been prepared using the co-precipitation method. The ferrite particles prepared were characterized using XRD, FTIR, and TEM and was confirmed to be in the nano-regime. Natural rubber composites were prepared with different loadings of nickel ferrite like 5, 15, 25, 50, 75 (in part per hundred rubber, phr). The mechanical, swelling, and magnetic properties were analyzed using standard methods. Dielectric measurements show that permittivity decreases with increase in frequency and increases with increase in ferrite loading. Tan delta value 156also was found to increase with filler loading which may be attributed to the presence of interfacial polarization.
