The nanoparticles of Zn0.80Co0.1Ni0.1Fe2O4 and ZnFe2O4 were synthesized via a micro emulsion procedure and then embedded into a polyvinyl alcohol matrix by an ultrasound-assisted in-situ emulsion. The result showed that the prepared nanoparticles of Zn0.80Co0.1Ni0.1Fe2O4 & ZnFe2O4 diffuse homogeneously in a polyvinyl alcohol matrix, maintaining the particle shape and size of the Zn0.80Co0.1Ni0.1Fe2O4 nanoparticles. Transmission electron microscope images revealed that polyvinyl alcohol chains have encircled the Zn0.80Co0.1Ni0.1Fe2O4 & ZnFe2O4 nanoparticles. The interaction between the polyvinyl alcohol and the nanoparticles in the prepared nanocomposites was confirmed by Fourier-transform infrared spectroscopy via the shifting of bands revealed from the Fourier-transform infrared spectra. Dielectric studies explained the decreasing trend by varying concentrations of nanoparticles with a constant polymer concentration. The dielectric constant and dielectric loss both revealed a decreasing trend by varying the concentration of the nanoparticles with a constant polymer concentrat...
