Investigation of the structural, magnetic, and electrical properties of epsilon-negative Bamboo/NiS2/(MnFe2O4)x/PVC metacomposites
Considerable attention has been focused on the unique and unexpected properties of lightweight, broad-spectrum, and high reflection loss (RL) metacomposites with adjustable electromagnetic characteristics. This research project aimed to investigate the structural, magnetic, and electrical attributes of Bamboo/NiS2/(MnFe2O4)x/PVC metacomposites, which display negative permittivity behavior as a novel material. When the mole value of MnFe2O4 was 0.0027 or lower, the presence of negative permittivity was detected at frequencies between 0–100 MHz and higher. The main reason for this was the easy creation of electrical percolation through the processed bamboo structure, which is crucial for achieving negative permittivity and high AC conductivity. The frequency-dependent variations in permittivity were in agreement with the Lorentz model. By altering the mole fraction of MnFe2O4 to adjust impedance, the electromagnetic absorption capabilities of the metacomposites were improved to − 25.87878 dB for a thickness of 1 mm. The findings presented in this study have the potential to pave the way for innovative developments in the field of negative permittivity metacomposites, facilitating the practical implementation of epsilon-negative materials and lightweight absorption properties in electromagnetic devices such as memristors, light-dependent resistors (LDRs), and low-frequency reflectors.
期刊介绍:
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
