摘要
随着电子设备和无线通讯的迅猛发展,电磁干扰问题也随之日益严重,迫切需要发展高性能的电磁屏蔽防护材料来减轻电磁波干扰危害。MXene(Ti_(3)C_(2)T_(x))是一种新型二维材料,具有超高的电导率和活跃的化学活性表面,因而展现出极其优异的电磁屏蔽性能。本文重点介绍了Ti_(3)C_(2)T_(x)的制备方法、结构特性以及电磁屏蔽机理,客观地综述和评价了近年来国内外关于Ti_(3)C_(2)T_(x)基薄膜和三维多孔材料在电磁屏蔽应用方面的重要研究进展,并分析了目前存在的主要问题。此外,从Ti_(3)C_(2)T_(x)的制备、结构调控、设计组装等方面展望了Ti_(3)C_(2)T_(x)基电磁屏蔽材料的发展方向及趋势,包括发展低成本绿色环保且高效的Ti_(3)C_(2)T_(x)制备工艺、解决Ti_(3)C_(2)T_(x)不耐氧化的问题、设计新型Ti_(3)C_(2)T_(x)电磁屏蔽材料结构及探究其他种类的MXenes电磁屏蔽材料,为开发下一代高电磁屏蔽性能材料提供新的思路和指导。
With the rapid development of electronic equipment and wireless communication in recent years,problems of electromagnetic interference are also becoming more and more serious.It is urgent to develop high performance electromagnetic interference(EMI)shielding materials to alleviate the damage of electromagnetic interference.MXene(Ti_(3)C_(2)T_(x)) is a novel kind of 2D material with ultrahigh electrical conductivity and unique chemically active surface,and therefore exhibits extremely excellent electromagnetic shielding performance.The preparation,structural feature and EMI shielding mechanism of Ti_(3)C_(2)T_(x) were focused and introduced in this paper,the latest research progress on EMI shielding applications of Ti_(3)C_(2)T_(x)-based films and 3D porous materials was objectively reviewed and evaluated,and the main problem at the present was analyzed.In addition,the future development direction and tendency of Ti_(3)C_(2)T_(x)-based EMI shielding materials from the aspects of preparation,microstructure control and structure design and so on were also prospected in this poper,based on current development needs including developing low-cost,green and efficient Ti_(3)C_(2)T_(x) preparation methods,solving the long-standing oxidation problem of Ti_(3)C_(2)T_(x),designing new structure of Ti_(3)C_(2)T_(x)-based EMI shielding materials and finding out other MXenes EMI shielding materials other than Ti_(3)C_(2)T_(x),which can provide new ideas and guidance for the further development of the next generation of high-performance EMI shielding materials.
