Abstract
In the dynamic landscape of wearable electronics, the demand for versatile electromagnetic interference (EMI) shielding materials is on the rise. Despite numerous studies on multifunctional EMI shielding fabrics, research on developing such materials using resource-efficient and cost-effective strategies is scarce. The present study introduces a pioneering approach to crafting simulation-engineered carbonized cotton-based EMI shielding fabrics with diverse multifunctionality by leveraging the strategy of electromagnetic (EM) simulations and ferrite decoration. The exceptional conductivity of carbonized cotton stemming from plasmonic electronic states, together with ferrite integration, plays a significant role in enhancing the EMI shielding ability of the fabrics. Ferrite integration is found to be instrumental in reducing the reflection and enhancing the absorption of EM radiations. EM simulations based on a double-layer fabric model demonstrated ~ 60 dB shielding effectiveness for a fabric with 0.75mm thickness, which is further verified via experimental testing. A comprehensive analysis of the EM parameters of the shielding fabric unveiled the existence of unique high-frequency negative permittivity, the high dielectric loss of the order of 10, multiple dielectric-magnetic relaxations, and high attenuation constant in the order of 103, which significantly contributed to the effective absorption of EM waves. Furthermore, the fabricated EMI shielding fabrics exhibit a plethora of desirable traits, including superior Joule heating performance, photo-thermal capabilities, efficient thermal management, and remarkable hydrophobicity. Consequently, the findings position the multifunctional simulation-engineered EMI shielding fabrics developed in this study as compelling contenders for futuristic applications in wearable electronics, aligning closely with policies emphasizing cost-effectiveness and sustainability.
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.
