Characterization, Optical and Conductivity Study of Nickel Oxide Based Nanocomposites of Polystyrene

Different concentrations of nickel oxide (NiO) nanoparticles were successfully inserted into polystyrene (PS) polymer matrix using the solution casting method. X-ray diffraction (XRD), Fourier transform infrared (FT-IR), High-resolution scanning electron microscope (HRSEM), and UV–Vis techniques are used to characterize nanocomposites. XRD, HRSEM, FT-IR results indicate that PS NiO have a good interaction high degree complexity. Using technique, absorbance nanocomposites is improved by increasing nanofiller content. Both Urbach energy (EU) optical gap (Eg) calculated relation Tauc model. Refractive indices values display raising trend with content which promote PS/NiO for use in photonic applications designing devices. Electrical conductivity also investigated. The electrical has increased significantly due uniform dispersion its Conduction achieved correlated barrier hopping (CBH).
