随着5G网络的普及和电子设备的小型化,电磁辐射给周围环境和人体带来了一定的危害,为此研制综合性能优异的新型电磁干扰屏蔽材料具有十分重要的意义.Ti3C2Tx MXene是一种新型二维材料,具有独特的层状结构、可调节的活性表面、超高电导率等特点,展现出优异的电磁屏蔽性能.近年来,关于Ti3C2Tx的制备方法和填料选择的报道层出不穷,然而从结构设计层面总结Ti3C2Tx基复合材料的工作却很少.高效的结构设计不仅能够减少填料的用量而且能够提高屏蔽效能.本文以结构为主线,对近年来Ti3C2Tx基电磁屏蔽材料的发展趋势进行了总结,通过分析屏蔽效能和屏蔽机制,重点总结不同的结构如多孔结构、分层结构、核壳结构、其他特殊结构及其复合结构对Ti3C2Tx基电磁屏蔽性能的影响及作用,并提出了目前Ti3C2Tx及其复合材料在作为电磁屏蔽材料使用时急需解决的关键科学和技术问题.最后对MXenes的发展前景进行展望.
With the popularity of 5G network and the miniaturization of electromagnetic equipment,electro-magnetic 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.Ti3C2Tx 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 Ti3C2Tx 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 Ti3C2Tx based electro-magnetic 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 per-formance of Ti3C2Tx based materials.And key scientific and technical issues that urgently need to be addressed when Ti3C2Tx and its composite materials are used as electromagnetic shielding materials were proposed.Finally,the development prospect of Ti3C2Tx MXene is prospected.
