“…However, the electrical conductivity of PVA is low, since it is a material of proton conduction [ 6 ], which limits its device applications in the pure form. Therefore, precise control of its electrical conductivity is essential to facilitate its utilization for practical device applications, including bioimplantable devices, resistive switching devices, and magnetic-controlled drug delivery devices [ 7 , 8 , 9 ]. Plasticizers, such as glycerol (GL), are a novel class of materials with many outstanding properties, including thermal steadiness, nonflammability, nondispersal, and extraordinary ionic conductivity [ 10 ].…”

Composite polymer membranes of poly(vinyl alcohol) (PVA) and iron oxide (Fe3O4) nanoparticles were produced in this work. X-ray diffraction measurements demonstrated the formation of Fe3O4 nanoparticles of cubic structures. The nanoparticles were synthesized by a coprecipitation technique and added to PVA solutions with different concentrations. The solutions were then used to generate flexible membranes by a solution casting method. The size and shape of the nanoparticles were investigated using scanning electron microscopy (SEM). The average size of the nanoparticles was 20±9 nm. Raman spectroscopy and Fourier-transform infrared spectroscopy (FTIR) were utilized to investigate the structure of the membranes, as well as their vibration modes. Thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC) demonstrated the thermal stability of the membranes and the crystallinity degree. Electrical characteristics of the thin membranes were examined using impedance spectroscopy as a function of the nanoparticles’ concentrations and temperatures. The resistivity of the fabricated flexible membranes was possible to adjust by controlled doping with suitable concentrations of nanoparticles. The activation energy decreased with the nanoparticles’ concentrations due to the increase in charge carriers’ concentrations. Therefore, the fabricated membranes may be applied for practical applications that involve the recycling of nanoparticles for multiple application cycles.

“…The phase and magnetic properties of iron oxide NPs were changed corresponding to their resistive states. At a high resistance state (HRS), iron oxide NPs are in the ferromagnetic state, but in a low resistance state (LRS), and the ferromagnetic state of iron oxide was changed through the migration of oxygen ions/oxygen vacancies under the electric field . Moreover, as also reported by Khan et al in 2020, a flexible asymmetric resistive switching device-based ZnO/Fe 2 O 3 heterojunction has been successfully fabricated through the spin coating method.…”

Despite extensive research into novel materials, iron oxides remain fascinating and attract considerable attention because of their versatility, stability, ease of fabrication, low cost, natural abundance, and environmental friendliness. Because of their wealth of magnetic, optical, and electrical properties, iron oxides are particularly multifunctional materials that can be integrated into various devices. In this article, we will discuss the applications of iron oxide thin films in electronics (spintronics devices), energy (batteries and solar cells or photovoltaics), and sensors (gas, humidity, strain, biosensors, and so on). We begin with the most recent forms and fabrication methods for iron oxide thin film, as well as a fundamental understanding of the material. Additionally, the application constraints of these devices are discussed, and the challenges, solutions, and prospects for electronic devices based on iron oxide are outlined.

“…Due to magnetic, optical and electrical properties, biocompatibility, eco-friendliness and low price [ 1 , 2 , 3 , 4 ], iron oxide nanoparticles (IONPs) have been used for preparation of multifunctional thin films and membranes with numerous applications. Thus, maghemite (γ-Fe 2 O 3 ) and magnetite Fe 3 O 4 nanoparticles (NPs) are two of the most important iron oxides for food safety (packing [ 5 ], insecticide extraction [ 6 ], sensing for contaminants [ 7 ]) in adsorption and photocatalytic processes (heavy metal detection and removal [ 8 ] and degradation of organic pollutants [ 9 , 10 , 11 , 12 , 13 , 14 ]), electronic field (batteries and magnetic storage media [ 1 , 15 ]) and theranostic applications [ 16 , 17 , 18 ]. When the particle size drops below 50 nm, and especially below 20 nm, their magnetic properties change considerably.…”

In recent years, iron oxides-based nanostructured composite materials are of particular interest for the preparation of multifunctional thin films and membranes to be used in sustainable magnetic field adsorption and photocatalysis processes, intelligent coatings, and packing or bio-medical applications. In this paper, superparamagnetic iron oxide (core)-silica (shell) nanoparticles suitable for thin films and membrane functionalization were obtained by co-precipitation and ultrasonic-assisted sol-gel methods. The comparative/combined effect of the magnetic core co-precipitation temperature (80 and 95 °C) and ZnO-doping of the silica shell on the photocatalytic and nano-sorption properties of the resulted composite nanoparticles were investigated by ultraviolet-visible (UV-VIS) spectroscopy monitoring the discoloration of methylene blue (MB) solution under ultraviolet (UV) irradiation and darkness, respectively. The morphology, structure, textural, and magnetic parameters of the investigated powders were evidenced by scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, Brunauer–Emmett–Teller (BET) measurements, and saturation magnetization (vibrating sample magnetometry, VSM). The intraparticle diffusion model controlled the MB adsorption. The pseudo- and second-order kinetics described the MB photodegradation. When using SiO2-shell functionalized nanoparticles, the adsorption and photodegradation constant rates are three–four times higher than for using starting core iron oxide nanoparticles. The obtained magnetic nanoparticles (MNPs) were tested for films deposition.
