Enhancing electromagnetic wave absorption with core‐shell structured SiO 2 @MXene@MoS 2 nanospheres

Abstract Material composition and structural design are important factors influencing the electromagnetic wave (EMW) absorption performance of materials. To alleviate the impedance mismatch attributed to the high dielectric constant of Ti 3 C 2 T x MXene, we have successfully synthesized core‐shell structured SiO 2 @MXene@MoS 2 nanospheres. This architecture, comprising SiO 2 as the core, MXene as the intermediate layer, and MoS 2 as the outer shell, is achieved through an electrostatic self‐assembly method combined with a hydrothermal process. This complex core‐shell structure not only provides a variety of loss mechanisms that effectively dissipate electromagnetic energy but also prevents self‐aggregation of…
