Heterodimensional structure with enhanced interface loss for microwave absorption and EMI shielding
The study of high-performance multifunctional electromagnetic materials is one of the inevitable challenges in the field of electromagnetic wave (EMW) absorption. In order to improve the attenuation ability of EMW and broaden the frequency range of absorbing materials, rational design of material structure and interface is an important way to optimize the effective absorption bandwidth (EAB). Therefore, enhanced-interface and strongly polarized CuS/Ti3C2TX composites were successfully synthesized by in-situ etching, sacrificial template and freeze-drying techniques. Its EMW absorption performance was improved by optimizing the hybridization ratio and loading content. The maximum reflection loss of CuS@Ti3C2TX (mass ratio = 5:5) is −54.6 dB and the maximum EAB covering the major of Ku band is 4.72 GHz due to the interface polarization, multiple scattering and dipole polarization. In addition, the electromagnetic interference shielding performance of CuS@Ti3C2TX (mass ratio = 3:7) is up to 23.9 dB. A new heterodimensional structure was developed by the spherical structure and lamellar, which realizes the broadband EMW absorption and electromagnetic protection.
