Abstract:
With the popularity of 5G network and the miniaturization of electromagnetic equipment, electromagnetic radiation has brought certain harm to the surrounding environment and human body. Therefore, it is of great significance to develop new electromagnetic interference shielding materials with excellent comprehensive performance. Ti
3C
2T
x MXene is a new type of two-dimensional material with unique layered structure, adjustable active surface, ultra-high conductivity and other characteristics. Thus, it exhibits an excellent electromagnetic shielding performance. In recent years, many researches on its preparation method and filler selection have been reported. However, there is little work to summarize Ti
3C
2T
x matrix composites from the structural design level. High-efficiency structural design can not only reduce the amount of filler, but also improve shielding effectiveness. This article takes the structure as the main thread and summarizes the development trend of Ti
3C
2T
x based electromagnetic shielding materials in recent years. By analyzing the shielding effectiveness and mechanism, the article focuses on summarizing the influence and role of different structures such as porous structure, layered structure, core-shell structure, other special structures, and their composite structures on the electromagnetic shielding performance of Ti
3C
2T
x based materials. And key scientific and technical issues that urgently need to be addressed when Ti
3C
2T
x and its composite materials are used as electromagnetic shielding materials were proposed. Finally, the development prospect of Ti
3C
2T
x MXene is prospected.
