Self‐Assembled MoS₂ Cladding for Corrosion Resistant and Frequency‐Modulated Electromagnetic Wave Absorption Materials from X‐Band to Ku‐Band

Small, Год журнала: 2023, Номер 19(52)

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.

Abstract Polarization at interfaces is an important loss mechanism for electromagnetic wave (EMW) attenuation, though the motion behavior of carriers in composed different types conductors has yet to be investigated. Tuning phase structure transition metal dichalcogenides (TMDs) MS 2 (M = Mo, V, W) by organics small molecule intercalation achieve modulation interfacial effective strategy, where 1T‐MS exhibits metallic properties and 2H‐MS semiconducting properties. To exclude contribution intrinsic TMDs materials, three (MoS , VS WS ), which also possess transitions, are Among them, composite excellent EMW absorption performance under synergistic effect polarization conduction loss. 1T‐MoS /MOF‐A best with RL min −61.07 dB a thickness 3.0 mm EAB 7.2 GHz 2.3 mm.
