The development of wearable multifunctional electromagnetic protective fabrics with multifunctional, low cost, and high efficiency remains a challenge. Here, inspired by the unique flower branch shape "Thunberg's meadowsweet" in nature, nanofibrous composite membrane hierarchical structure was constructed. Integrating sophisticated 0D@2D@1D structures multiple heterointerfaces can fully unleash application potential membrane. targeted induction method used to precisely regulate formation site morphology metal-organic framework precursor, intelligently integrate heterostructures enhance dielectric polarization, which improves impedance matching loss mechanisms wave absorbing materials. Due synergistic enhancement electrospinning-derived carbon nanofiber "stems", MOF-derived nanosheet "petals" transition metal selenide nano-particle "stamens", CoxSey/NiSe@CNSs@CNFs (CNCC) obtains minimum reflection value (RLmin) -68.40 dB at 2.6 mm maximum effective absorption bandwidth (EAB) 8.88 GHz thin thickness 2.0 filling amount only 5 wt%. In addition, multi-component heterostructure endow fibrous excellent flexibility, water resistance, thermal management, other properties. This work provides perspectives for precise design rational fabrics.

Electromagnetic wave (EMW) absorbing materials have an irreplaceable position in the field of military stealth as well electromagnetic pollution control. And order to cope with complex environment, design multifunctional and multiband high efficiency EMW absorbers remains a tremendous challenge. In this work, we designed three-dimensional porous structure via salt melt synthesis strategy optimize impedance matching absorber. Also, through interfacial engineering, molybdenum carbide transition layer was introduced between selenide nanoparticles carbon matrix improve absorption behavior The analysis indicates that number components heterogeneous interfaces significant impact on performance absorber due mechanisms such polarization conduction loss by engineering.

Опубликована: Авг. 27, 2023

Reasonable composition design and controllable structure are effective strategies for harmonic electromagnetic wave (EMW) adsorption of multi-component composites. On this basis, the hybrid MoS2 /CoS2 /VN multilayer with triple heterogeneous interface is prepared by simple stirring hydrothermal, which can satisfy synergistic interaction between different components obtain excellent EMW absorption performance. Due to presence multiple interfaces, composites will produce strong interfacial polarization, while defects in sample become center resulting dipole polarization. structural composite material, material not only has good conductive loss polarization loss, but also maintain stability simulated seawater, enhance corrosion resistance. The dual functions resistant microwave achieves a minimum reflection (RL) -50.48 dB an bandwidth up 5.76 GHz, covering both X-band Ku-band. Finally, study provides reference development materials based on transition metal nitrides.
