"Cobalt-based ferrite nanocomposites have been envisioned as the most promising materials to be utilized in various optical and electronic devices, including transistors, electronic gates, and photovoltaic cells. Here, a casting method is used to fabricate polystyrene/cobalt ferrite (PS/CoFe2O4) nanocomposite films (NFs) with different CoFe2O4 nanoparticle contents (0–6.3 wt%), followed by characterizing their chemical, microstructural, optical, and dielectric properties. The absorbance of PS/CoFe2O4NFs increases to 70% and the transmittance decreases to 75% at a wavelength of = 580 nm when the CoFe2O4 content increases to 6.3 wt%. Moreover, the absorption coefficient increases from 378 cm1 for pure PS to 630 cm1 for NFs with CoFe2O4 content of 6.3 wt% at a photon energy of 4.44 eV. The energy gap of allowed and forbidden indirect transitions is reduced from 3.3 to 2.4 eV and 3.2 to 2 eV when the nanoparticle content increases from 0 to 6.3 wt%. Mean while, the extinction coefficient and refractive index show increasing trends at = 880 nm, increasing from 0.5 × 10–3 to 2 × 103and 1.8 to 2.5, respectively. It is found that the real and imaginary parts of the dielectric constant are enhanced with increasing the CoFe2O4content.The results of AC electrical properties indicate that the corresponding electrical conductivity and dielectric constant increase by about 58% and 35% with the increase in the CoFe2O4content at a frequency of 100 Hz. Therefore, the PS/CoFe2O4NFsmay pave the way for potential applications in nanoelectronics and nanodevices."
