Novel honeycomb-structured Ag@Ti3C2Tx composites are prepared by a microwave-assisted synthesis method using polymethyl methacrylate as an expendable template. The resulting Ag@Ti3C2Tx composites retain their original spherical morphology and exhibit hydrophobic performance, low thermal conductivity, and excellent electromagnetic interference (EMI) shielding performance. Remarkably, the Ag-1.8@Ti3C2Tx composite attains electromagnetic interference shielding performance with a maximum average shielding effectiveness of 39.36 dB in the X-band and 43.64 dB in the Ku-band. This outstanding performance is the result of conduction loss, interface polarization between Ag nanoparticles and Ti3C2Tx nanosheets, and multi-reflection and scattering caused by the hollow structure in the honeycomb-structured Ag@Ti3C2Tx composites. Overall, the honeycomb-structured Ag@Ti3C2Tx composites possess merits such as light weight, flexibility, hydrophobicity, and EMI shielding performance, suggesting great application potential in smart electronic devices.

柔性疏水蜂窝结构 Ag@Ti3C2Tx 复合材料的电磁干扰屏蔽性能
使用聚甲基丙烯酸甲酯作为消耗性模板，通过微波辅助合成方法制备了新型蜂窝结构 Ag@Ti 3 C 2 T x复合材料。所得的 Ag@Ti 3 C 2 T x复合材料保留了其原始的球形形态，并表现出疏水性能、低导热性和出色的电磁干扰 (EMI) 屏蔽性能。值得注意的是，Ag -1.8 @Ti 3 C 2 T x复合材料获得了电磁干扰屏蔽性能，在 X 波段的最大平均屏蔽效率为 39.36 dB，在 K u波段为 43.64 dB-乐队。这种出色的性能是传导损耗、Ag 纳米颗粒和 Ti 3 C 2 T x纳米片之间的界面极化以及蜂窝结构 Ag@Ti 3 C 2 T x复合材料中的中空结构引起的多反射和散射的结果。总体而言，蜂窝结构的Ag@Ti 3 C 2 T x复合材料具有重量轻、柔韧性、疏水性和EMI屏蔽性能等优点，在智能电子设备中具有巨大的应用潜力。
