Abstract
This study investigates the structural, dielectric, optical, and electrical properties of eco-friendly polyvinyl alcohol (PVA) and polyvinyl pyrrolidone (PVP) matrices embedded with zinc manganite nanoparticles (ZnMn2O4NPs). The nanocomposites films were prepared using a casting method for potential applications in flexible electrochemical devices. FTIR spectroscopy confirmed the successful incorporation of ZnMn2O4NPs into the polymeric matrix. UV–Vis absorption analysis revealed an increase in absorbance with increasing ZnMn2O4 nanoparticle content. Among the various blend nanocomposites, the lowest bandgap energy was observed for the sample containing 2.5 %ZnMn2O4 NPs. Measurements of electrical conductivity, dielectric characteristics, and complex impedance were made for all prepared films. The findings showed that as frequency and nanofiller concentration increased, so did AC conductivity and dielectric characteristics. Overall, the PVA/PVP-2.5 % ZnMn2O4 nanocomposite exhibited superior properties compared to the pure polymer blend. This sample demonstrated optimal electrical conductivity and dielectric constant. These findings suggest that by carefully adjusting the ZnMn2O4 concentration, it is possible to fine-tune the dielectric, optical, and electrical properties of these nanocomposite films. This versatility offers promising potential for applications in optoelectronic devices, energy storage devices, and nanodielectric materials.

期刊介绍:
Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics.
Results in Physics welcomes three types of papers:
1. Full research papers
2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as:
- Data and/or a plot plus a description
- Description of a new method or instrumentation
- Negative results
- Concept or design study
3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
