“…The optical constants of PEO À PEDOT=NiZnFeO 4 NPs nanocomposite films, such as extinction coefficient and refractive index, were determined using transmittance and reflectance UV-Vis spectra and established methods found in the literature. 3,5,29,30,32 The transmittance spectra of the PEO À PEDOT film displayed a significant increase from 0% to approximately 86% as the incident photon wavelength increased from 300 to 400 nm, with no discernible changes observed beyond 400 nm (Figure 5a). The introduction of NiZnFeO 4 NPs resulted in a decrease in the transmittance level due to the presence of free electrons in the NPs that can absorb incident photons with lower energy.…”

“…Conductive polymers have garnered attention from both scientific and industrial perspectives due to their exceptional optical, electrical, and electrochemical properties, as well as their facile processability, controllable chemical properties, and the ability to undergo reversible doping‐dedoping processes 1–3 . The optoelectrical properties of the conductive polymers are related to their conjugated nature and to the polarons formation, which is localized along the polymer chains because of the electron–phonon coupling 4–6 .…”

Polyethylene oxide‐poly(3,4‐ethylenedioxythiophene) (PEO‐PEDOT) nanocomposite films ‐ incorporated with NiZnFeO4 nanoparticles (NPs) were deposited using a dip‐coating technique. X‐ray diffraction (XRD) analysis revealed peaks at 35.4, 43.2, 54.5, and 56.3° diffraction angles, corresponding to NiZnFeO4NPs diffraction planes of 311, 400, 422, and 511, respectively. The PEO‐PEDOT film exhibited a smooth amorphous nature with a sheet nanostructure behavior. The incorporation of NiZnFeO4NPs NPs into the PEO‐PEDOT nanocomposite films led to an increase in surface roughness and thermal stability. The nanocomposite films also exhibited sheet nanostructure behavior as observed by SEM micrographs. The bandgap energies of the films, as deduced from the Tauc plot, exhibited a monotonic decrease from 3.91 to 3.60 eV as the NiZnFeO4NPs concentration increased from 0 to 8 wt%. A mathematical model was formulated to predict the bandgap energies versus NiZnFeO4NPs concentration. Additionally, the electrical conductivity of the nanocomposite films increased monotonically from 0.46 to 1.30 mS cm−1 as the NiZnFeO4NPs concentration increased from 0 to 8 wt%, as determined by 4‐point probe. The observed correlation between the optical and electrical properties of the nanocomposite films indicates promising prospects for utilizing these materials in optoelectronic devices.

This study investigated the effect of ionic‐electronic coupling on the percolation phenomenon of polyethylene oxide (PEO)/rGO nanocomposite films by adding KOTf because the rGO exhibits electronic conductivity and KOTf exhibits ionic conductivity. The electrical conductivity curve of PEO/rGO nanocomposite films exhibits a sharp rise in the percolation zone, followed by constant values in the conductive zone, indicating the formation of rGO conductive pathways through the PEO matrix. On the other hand, introducing KOTf in PEO/rGO nanocomposite films increases the maximum electrical conductivity from to , due to the high ionic‐electronic coupling through the polymer matrix at the interface between phase‐separated regions. Scanning electron micrographs revealed the distribution and morphology of PEO/rGO and PEO/rGO/KOTf nanocomposite films. Finally, the feasibility of using PEO/rGO and PEO/rGO/KOTf nanocomposite films in the conductive zone as an electrochemical charge storage device is investigated. We can conclude that PEO/rGO/KOTf nanocomposite films can be used in several potential applications, including high‐performance UV‐photodetectors, photoactive layers in solar cells, and energy storage devices.

In this research, we demonstrate the influence of compelled iron nanoparticles (FeNPs) up to the surface on the percolation phenomenon and the electrical conductivity of the PEO/FeNPs nanocomposite films by applying a uniform magnetic field. The electrical conductivity of the PEO/FeNPs nanocomposite films exhibits a sharp increase from to 390 S∙cm−1 as the FeNPs volume fraction rises from 0.12 to 0.24, where the FeNPs form percolating networks and interparticle contacts. Applying a magnetic field drives the FeNPs towards the surface of the PEO/FeNPs nanocomposite films and consequently increases the electrical conductivity of the PEO/FeNPs nanocomposite films up to 1960 S∙cm−1. The morphological features of the PEO/FeNPs nanocomposite films with different concentrations of FeNPs upon applying a magnetic field towards the surface were investigated. Finally, the corrosion protection efficiency of PEO/FeNPs nanocomposite films increases as FeNPs increase from an insulating zone to a conductive zone. On the other hand, applying a magnetic field drives the FeNPs towards the PEO/FeNPs nanocomposite surfaces, increasing the corrosion protection efficiency from 92.67% to 98.09%.Highlights The nanoparticle positioning effect on nanocomposite films is investigated. The electrical conductivity of PEO/FeNPs nanocomposite film reaches 390 S∙cm−1. Electrical conductivity increases to 1960 S∙cm−1 upon nanoparticle positioning. Corrosion protection efficiency increases to 98.09% after nanoparticle positioning.
