Abstract
The fabrication of nano-materials with delicate microstructure design and suitable multicomponent allocation is considered as a promising approach to meet the requirements of lightweight, high efficiency, and broadband absorption for electromagnetic wave (EMW) absorbers. Toward this end, nickel/carbon@zirconium dioxide core–shell nanofibers composited with polyurethane were successfully prepared through flexible electrospinning, carbonization, and a subsequent resin curing process. Profiting from the synergistic coactions of constituents and unique morphology, the ternary nanocomposites displayed the minimum reflection loss of − 61.7 dB at 17.1 GHz, and an ultra-broad bandwidth up to 8.3 GHz. In-depth investigation through electromagnetic parameters analysis and electric field distribution simulation indicated that the introduction of zirconium dioxide brought about the optimal impedance matching, while the existence of nickel and abundant heterogeneous interfaces contributed to diverse attenuation pathways, including interface polarization, dipoles polarization, conductivity loss, and magnetic loss. Thus, this study paved new research avenues for the design and synthesis of one-dimensional high-performance microwave absorbing materials, and enriched the application range of polyurethane matrix composites.
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.
