Excellent electromagnetic interference shielding of multi-layered thermoplastic poly-urethane nanocomposites with CoFe2O4 nanoparticles and graphite
This work presents the design and development of multi-layered polymer-based nanocomposites that effectively block electromagnetic (EM) radiation by incorporating magnetic CoFe2O4 nanoparticles (NPs) and conductive graphite on a thermoplastic polyurethane (TPU) matrix. The sonochemical method was employed to produce CoFe2O4 NPs with a high degree of purity. The melt mixing process followed by compression molding was utilized to generate individual layers of TPU containing CoFe2O4 NPs (F-TPU) and graphite (G-TPU) at a thickness of around 0.8 mm. Further, three mono-layers of either F-TPU or G-TPU were stacked in an identical and alternating fashion to create TPU-based multi-layered nanocomposites F/F/F, G/G/G, F/G/F, and G/F/G, respectively. The electromagnetic interference (EMI) total shielding effectiveness (SET) in the X-band frequency range of 8.2–12.4 GHz was investigated and observed to be 3.7 dB, 33.8 dB, 23.9 dB, and 54.0 dB for F/F/F, G/G/G, F/G/F, and G/F/G, respectively. This research offers a guide for engineers looking to create superior EMI shielding materials, which have potential uses in radar security and information communications.
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.
