Abstract

Abstract: Advanced high-performance microwave absorber development now revolves around achieving better microwave absorption performance and intelligent electromagnetic property control. Effectively adjusting electromagnetic microwave dissipation qualities throughout a wide frequency range has been mostly unexplored, particularly for manufactured absorbers. Innovative and high-performance absorber materials are produced and analyzed in this study. Solvothermal preparation is used to synthesize polygonal-shaped CuCo2 S4 particles that are embellished with Cu2 S particles. The permittivity and permeability of polygonal CuCo2 S4 particles decorated with Cu2 S particles are significantly altered, which further affects the nanocomposite's performance in terms of microwave absorption. At a filler loading of 40 wt percent, the composite exhibits exceptional microwave absorption capabilities, and at a thin thickness of 1.5 mm, its effective absorption bandwidth (EAB) approaches 4.5 GHz, covering the whole X-band frequency range. The produced composite has outstanding dissipation qualities owing to the synergistic effects of numerous attenuation mechanisms and hetero-interfaces, where the ideal microwave dissipation strength is up to −32 dB.
