This work studies the impact of positioning nickel nanoparticles (Ni-NPs) on the surface of doped (P84-PEO) nanocomposite films by using an ultrauniform magnetic field as a model for positioning magnetic NPs inside a polymeric matrix. This process is used to achieve desired and adjustable optoelectronic properties and to obtain new optical and electrical characteristics.P84-PEO copolymer doped with Ni-NPs exposed to a 450 mT magnetic field during the preparation give rise to a momentous increase in surface roughness, surface reactivity, and modified optical parameters, besides forming Ni oxides on the surface. Based on X-ray photoelectron spectroscopy experiments, substantial extra shifts occurred in the binding energies of photo-excited electrons from the O1s and C1s core levels. Additionally, the deconvoluted O1s spectra displays an additional photoelectron peak at 530.0 eV, most likely attributed to oxidized Ni-NPs at the surface. Moreover, optical and structural properties were studied using UV-Vis and PL spectroscopy and X-ray diffraction.

“…The increase in the refractive index values as the magnetic field towards the surface increases (Figure 9D) can be attributed to the decrease in the film polarizability due to the driving of NiNPs towards the surface and consequently changing in the NiNPs distribution in the nanocomposite. 32 In addition, driven NiNPs towards the surface leads to an increase in the absorption coefficient and a decrease in the transmitted and reflected light from the nanocomposite films.…”

This work presents the effect of driven nickel nanoparticles (NiNPs) towards the surface of (PS‐PANI)/NiNPs nanocomposite upon the application of a uniform magnetic field. The purpose is to obtain distinguishable optoelectronic and electrical properties. This process increases the surface roughness and its reactivity, and enables the tuning of the optical and electrical properties. Based on the results from X‐ray photoelectron and Fourier‐transform infrared spectroscopies, the magnetically‐driven NiNPs to the surface are oxidized, forming NiONPs and NiOHNPs. This oxidation effect transforms the surface from a hydrophilic to a hydrophobic state. In addition, the optical bandgap energy decreases from 4.04 to 3.77 eV, and the electrical conductivity increases from 12.77 μS/cm to 57.80 μS/cm and 77.52 μS/cm, for 50 and 100 mT magnetic fields, respectively, which is attributed to the well‐dispersed magnetic nanoparticles in the PS‐PANI polymer matrix, resulting in a high homogeneous nanocomposite film.

“…Ajmal and Islam 17 examined the dispersion of nickel ferrite and zinc ferrite in PANI and reported that Ni 0.5 Zn 0.5 Fe 2 O 4 had a high conductivity value in the high frequency band. Henaish et al 18 prepared NiAl‐ferrite/PANI/x (PANI) nanocomposite films ( x = 0.2, 0.4, 0.6, and 0.8) by solution casting method. The results confirm that the formation of spinel ferrite and the inclusion of nano‐sized ferrite particles in the PANI matrix.…”

Electrical conductivity is emerging as one of the most essential material's qualities of the 21st century due to the lightning‐fast advancements in the electronics sector and the continuously improving electrical goods. As conductive materials are used in the majority of the modern items we use, including power sources, energy generating systems, electrical circuits, sensors, and many others, continuing advancement in this field is very crucial. The novelty of this work lies in the dispersion of ferrite nanoparticles, which was synthesized using egg albumen to enhance the electrical behavior of PANI polymer films. In this research work, a simple casting approach was used to ex situ polymerize aniline to fabricate ultrathin and flexible CuFe2O4 distributed PANI films for electrical conductivity applications. The combustion approach was used to produce the copper ferrite nanoparticles, while egg albumen was not only used as the fuel but also it was used a capping agent to control the size of ferrite NPs with a size much lower than that already reported. Studies on the structural, morphological, and electrical properties of pure and various weight percent of (1 , 3 , and 5 wt%) CuFe2O4 loaded PANI films were performed. Comparing the different films, the 5 wt% CuFe2O4 dispersed PANI films exhibited remarkable and greatly improved permittivity and electrical conductivity with low dielectric loss. This indicates the 5 wt% CuFe2O4 dispersed PANI films have the prospective uses in high‐tech industries where there is a need for flexible, thin, and lightweight high electrical conducting materials with lesser loss factor.
