Abstract

Remarkably low permittivity at plasma frequency for epsilon-near-zero (ENZ) materials has garnered significant interest. This study reports a flexible magnetically driven radio frequency ENZ material. Cobalt nanoparticles, cobalt–nickel, and iron-cobalt–nickel alloy nanoparticles were in situ synthesized on the inner walls of carbon nanotubes (denoted as Co@CNTs, CoNi@CNTs, and FeCoNi@CNTs) and subsequently incorporated into thin films with waterborne polyurethane (PU). Notably, in the FeCoNi@CNTs-PU film, the real permittivity transfers from negative to positive, achieving ENZ performance at 45 MHz. Additionally, the findings indicate a gradual decrease in plasma frequency associated with the alloying process. The underlying mechanisms have been investigated through theoretical calculations, which reveal that as metals are synthesized and alloyed on the inner walls of CNTs, the band structure experiences a flattening effect and non-parabolic enhancement, leading to an increase in effective electron mass. Furthermore, the FeCoNi@CNTs-PU film exhibits exceptional magnetic driving capabilities and flexibility. This positions ENZ materials as promising candidates for applications in magnetically driven actuators and implantable electronic devices.

中熵FeCoNi合金颗粒掺杂碳纳米管及其衍生物的epsilon近零和磁驱动性能
近零介电常数(ENZ)材料在等离子体频率下的低介电常数引起了人们极大的兴趣。本研究报告了一种柔性磁驱动射频ENZ材料。钴纳米颗粒、钴镍纳米颗粒和铁钴镍合金纳米颗粒在碳纳米管(表示为Co@CNTs、CoNi@CNTs和FeCoNi@CNTs)的内壁上原位合成,随后与水性聚氨酯(PU)结合成薄膜。值得注意的是,在FeCoNi@CNTs-PU薄膜中,实际介电常数从负转移到正,在45 MHz时实现ENZ性能。此外,研究结果表明,等离子体频率逐渐降低与合金化过程有关。通过理论计算研究了其潜在的机制,结果表明,当金属在CNTs内壁上合成和合金化时,能带结构经历了平坦效应和非抛物线增强,导致有效电子质量增加。此外,FeCoNi@CNTs-PU薄膜表现出卓越的磁驱动能力和灵活性。这使得ENZ材料成为磁驱动执行器和植入式电子设备应用的有前途的候选者。

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.
