This study investigates the fabrication of new polyvinyl alcohol (PVA)–silicon nitride (Si3N4)–cobalt ferrite (CoFe2O4) nanocomposites to use them in various electrical and electronics fields. The dielectric properties of PVA–Si3N4–CoFe2O4 nanocomposites are examined in frequency range from 100 Hz to 2 MHz. The results indicate that the dielectric constant and dielectric loss of PVA–Si3N4–CoFe2O4 nanocomposites are reduced, while the electrical conductivity is increased with increasing of the frequency. The dielectric constant, dielectric loss, and electrical conductivity of PVA are raised with rising of the Si3N4–CoFe2O4-nanoparticles' content. The obtained results of dielectric properties demonstrate that the PVA–Si3N4–CoFe2O4 nanocomposites are useful for different electrical and electronics fields.

KEY WORDS: polyvinyl alcohol (PVA), Si3N4, CoFe2O4, nanocomposites, dielectric properties, conductivity
