Abstract:

 This study aims to synthesize a new type of nanocomposites based on polystyrene (PS)-poly(methyl methacrylate) (PMMA) blended with ferrite (ZnNiFe2O4) nanoparticles using a casting method. The results showed that the FE-SEM analysis confirmed that the (ferrite) nanoparticles have a homogeneous distribution in the PS/PMMA matrix. The dielectric properties showed that at lower frequencies, the dielectric constant (ε') shows high values; as the frequency increases, the values of (ε') decrease. At low applied frequencies, the dielectric loss (ε″) values are high; however, as the frequency increases, they decrease. The A.C. electrical conductivity (σA.C.) of nanocomposites increases with increasing frequency. As the concentration of ferrite nanoparticles increases, so do the dielectric constant, dielectric loss, and A.C. electrical conductivity. Good linear attenuation coefficients for gamma radiation are found in films with varying weight percentages of ferrite and PS-PMMA blends.
