Abstract:

This paper concentrates on innovative preparation of FeS nanoparticles-modified Ti₃C₂ two-dimensional nanoscale absorbing material, exploring its application potential in the field of radiation-proof polyester clothing fabrics. Through hydrothermal composite method, we successfully modified FeS nanoparticles uniformly and stably on Ti₃C₂ nanosheets to prepare a sandwich-like FeS@Ti₃C₂ composite. Through analyzing the phase structure and purity, the optimal preparation conditions were obtained (pH of 5, temperature of 120 ℃, holding time of 4 h, and raw material ratio of Fe:S:Ti = 1:1:1). The primary crystal phases identified were FeS and Ti₃C₂, both free from impurities. The electromagnetic wave (EMW) attenuation properties of FeS@Ti₃C₂ were investigated using impedance matching, dielectric constant, complex permeability, Cole–Cole plots, and minimum reflection loss measurements. FeS@Ti₃C₂ composite has a reflection loss of − 24.60 dB at 14.3 GHz and matching thickness of 2.2 mm. The FeS@Ti₃C₂ material exhibits exceptional EMW absorption performance. The EMW absorption capacity of Ti₃C₂ is significantly enhanced, allowing the composite to maintain an efficient absorbing effect across a wide frequency range. Benefiting from the high conductivity and mechanical strength of Ti₃C₂, the magnetic loss mechanism of FeS is introduced to achieve impedance matching and broadband absorption.
