Abstract:

Rational construction of heterointerfaces represents an effective strategy for exploring high-performance electromagnetic wave absorption. This study employs a simple two-step hydrothermal method to synthesize petal-clustered WS2/MnFe2O4/GNs (where GNs denotes graphene) hybrid materials. WS2 uniformly coats the polyhedral MnFe2O4 particles attached to the GNs surface, forming a multi-layer three-dimensional hetero-structure. By adjusting the MnFe2O4/GNs loading, the electromagnetic wave absorption properties of the ternary hybrid material can be effectively tuned. At a MnFe2O4/GNs loading of 20%, the minimum reflection loss reaches −44.50 dB, with a maximum effective absorption bandwidth of 4.08 GHz. This is attributed to the multilevel microstructure formed by flower-like WS2, polyhedral MnFe2O4, and GNs.
