电子设备的电磁辐射问题日益严重,开发高性能电磁屏蔽材料是现实的迫切需求.MXene由于其独特的层状结构、丰富的表面基团、优异的力学性能和突出的导电性,被认为在电磁屏蔽方面具有潜在的应用前景.为获得轻质、高效、稳定的电磁屏蔽材料,多种改性方法被用于提高MXene材料的电磁屏蔽效能,如通过定量控制MXene层状结构构建三维多孔、多层和插层等多种形态,通过氧化、掺杂、热处理和接枝等手段调控MXene表面终止基团及将MXene与其他材料杂化组装获得其他性能等.本文从结构设计、表面改性、复合杂化三方面综述了近几年国内外对MXene材料改性的研究进展,并对其提高电磁屏蔽效能进行了比较.
To develop high-performance shielding materials is currently emergency and important to erase the electromagnetic radiation concern.MXene is considered to have potential applications in electromagnetic shield-ing due to its unique layered structure,abundant surface groups,excellent mechanical properties and outstanding electrical conductivity.In order to obtain lightweight,efficient and stable electromagnetic shielding materials,various modification methods have been used to improve the electromagnetic shielding efficacy of MXene materials,such as constructing various morphologies such as three-dimensional porous,multilayer and inter-calated layers by quantitatively controlling the MXene layered structure,modulating the termination groups on the surface of MXene by means of oxidization,doping,heat treatment,and grafting,as well as hybridizing and assembling MXene with other materials to obtain other properties,etc.In this paper,the research progress on the modification of MXene materials at home and abroad in recent years is summarized from the aspects of structural design,surface modification,and composite hybridization,and compares their improvement in electromagnetic shielding effectiveness.
