Abstract

With the growing threat of electromagnetic interference, developing lightweight and flexible multiband protection materials to shield humans from harmful electromagnetic interference is becoming particularly crucial. However, existing protection materials are bulky and designed primarily for single-band electromagnetic waves. This paper constructs bismuth/tungsten oxide/multi-walled carbon nanotube/polyacrylonitrile (Bi/WO₃/MWCNTs/PAN) nanofiber composites with multilevel nanostructures through electrospinning and post-processing technology for effective NIR/UV/X-ray Multiband Electromagnetic Protection. The porous structure, combined with the strong absorption capabilities of MWCNTs for low-frequency electromagnetic waves and high photoelectric effects of high atomic number materials (Bi/WO₃), synergistically achieves remarkable electromagnetic protection performance. This includes 99.6 % near-infrared shielding and 99.95 % against ultraviolet (thickness: 0.12 mm), along with 55.2 % X-ray attenuation and a mass attenuation coefficient of 13.94 cm² g⁻¹ at 33 keV (thickness: 1.92 mm). Light weight (0.3 g cm⁻³), fantastic flexibility, and moisture permeability (9.22 kg m⁻² d⁻¹) endow the material with outstanding wearable performance. In addition, Bi/WO₃/MWCNTs/PAN also possesses excellent thermal insulation performance (36.96 mW m⁻¹ K⁻¹), temperature resistance (289.8 °C), and good electrical insulation. These exceptional performances demonstrate its enormous potential for application in electromagnetic shielding and provide new ideas for designing advanced multiband electromagnetic protection materials.

构建用于近红外/紫外/ x射线多波段电磁防护的多层纳米结构纤维复合材料

随着电磁干扰的威胁日益严重，开发轻量化、柔性的多波段防护材料来保护人体免受有害电磁干扰变得尤为重要。然而，现有的保护材料体积庞大，主要是为单波段电磁波设计的。本文通过静电纺丝和后处理技术，构建了具有多层纳米结构的铋/氧化钨/多壁碳纳米管/聚丙烯腈（Bi/WO3/MWCNTs/PAN）纳米纤维复合材料，用于有效的近红外/紫外/ x射线多波段电磁防护。多孔结构与MWCNTs对低频电磁波的强吸收能力和高原子序数材料（Bi/WO3）的高光电效应相结合，协同实现了卓越的电磁防护性能。这包括99.6%的近红外屏蔽和99.95%的紫外线（厚度：0.12 mm），以及55.2%的x射线衰减和13.94 cm2 g−1的质量衰减系数在33 keV（厚度：1.92 mm）。轻质（0.3 g cm−3）、极好的柔韧性和透湿性（9.22 kg m−2 d−1）使材料具有出色的耐磨性能。此外，Bi/WO3/MWCNTs/PAN还具有优异的保温性能（36.96 mW m−1 K−1）、耐温性能（289.8℃）和良好的电绝缘性。这些优异的性能显示了其在电磁屏蔽方面的巨大应用潜力，为设计先进的多波段电磁保护材料提供了新的思路。

期刊介绍： The journal Carbon is an international multidisciplinary forum for communicating scientific advances in the field of carbon materials. It reports new findings related to the formation, structure, properties, behaviors, and technological applications of carbons. Carbons are a broad class of ordered or disordered solid phases composed primarily of elemental carbon, including but not limited to carbon black, carbon fibers and filaments, carbon nanotubes, diamond and diamond-like carbon, fullerenes, glassy carbon, graphite, graphene, graphene-oxide, porous carbons, pyrolytic carbon, and other sp2 and non-sp2 hybridized carbon systems. Carbon is the companion title to the open access journal Carbon Trends. Relevant application areas for carbon materials include biology and medicine, catalysis, electronic, optoelectronic, spintronic, high-frequency, and photonic devices, energy storage and conversion systems, environmental applications and water treatment, smart materials and systems, and structural and thermal applications.
