摘要: 随着无线通信与电子设备的快速发展, 电磁污染问题日益严重, 开发兼具“薄、轻、宽、强”特性的电磁波吸收材料具有重要意义。Ti3C2Tx MXene具有较高的电导率、丰富的表面官能团、可调的层间结构以及较大的比表面积, 可通过导电损耗、偶极极化、缺陷极化、界面极化以及多重反射与散射等途径衰减电磁波, 已成为电磁波吸收领域的重要候选材料。然而, 过高的电导率容易引起阻抗失配, 其吸波性能还受到制备工艺、表面化学、片层结构、复合组分和微观形貌的共同影响。本文以Ti3C2Tx MXene及其复合材料为主要对象, 分析不同刻蚀/剥离条件与复合组分对材料结构、电磁参数及吸波性能的影响。首先介绍了Ti3C2Tx MXene的组成及其基本性质, 重点分析Ti3C2Tx MXene的导电性、力学性能和氧化稳定性。随后总结不同刻蚀与剥离方法对Ti3C2Tx MXene片层结构和缺陷的影响, 并建立制备参数与吸波性能之间的联系。在此基础上, 系统梳理纯Ti3C2Tx MXene及其介电、磁介电复合吸波材料的研究进展, 重点讨论碳材料、聚合物和陶瓷对导电网络与界面极化的调节作用, 以及磁性金属、合金和铁氧体在引入磁损耗、改善磁介电协同和优化阻抗匹配方面的作用。最后, 对Ti3C2Tx MXene吸波材料的关键挑战和未来发展方向进行了展望。

Abstract: With the rapid development of wireless communications and electronic devices, electromagnetic pollution has become an increasingly serious concern, creating a strong demand for electromagnetic wave absorbers that are thin, lightweight, broadband, and highly efficient. Ti3C2Tx MXene has emerged as a promising candidate owing to its high electrical conductivity, abundant surface terminations, tunable interlayer structure, and large specific surface area. These characteristics enable electromagnetic wave attenuation through conduction loss, dipolar polarization, defect polarization, interfacial polarization, and multiple reflection and scattering. However, its excessively high conductivity may cause impedance mismatch, while its absorption performance is jointly governed by the preparation process, surface chemistry, sheet structure, composite constituents, and microstructural configuration. Accordingly, this review focuses on Ti3C2Tx MXene and its composites and examines the effects of different etching and delamination conditions and composite constituents on their structures, electromagnetic parameters, and absorption performance. The composition and fundamental properties of Ti3C2Tx MXene are first introduced, with particular emphasis on its electrical conductivity, mechanical properties, and oxidation stability. Various etching and delamination methods are then summarized, and their effects on the sheet structure and defect characteristics of Ti3C2Tx MXene are discussed to clarify the relationship between preparation parameters and electromagnetic wave absorption. Recent advances in pristine Ti3C2Tx MXene and its dielectric and magnetic-dielectric composites are subsequently reviewed. Particular attention is paid to how carbon materials, polymers, and ceramics regulate conductive networks and interfacial polarization, as well as how magnetic metals, alloys, and ferrites introduce magnetic loss, promote dielectric-magnetic synergy, and improve impedance matching. Finally, the key challenges and future development directions of Ti3C2Tx MXene-based electromagnetic wave absorbers are discussed.
