摘要
MXene是一大类二维过渡金属碳氮化合物,其丰富的组分、二维原子层结构、金属电导和活性表面等特性使其与不同波段的电磁波(可见光、红外、太赫兹、微波波段等)产生独特的相互作用,并衍生了多种电磁功能应用.在红外波段,MXene具有宽域的红外辐射特性,活性表面使其具备可调的红外吸收.近年来,MXene的上述性质引起了广泛研究兴趣.本文首先对不同MXene组分的本征红外辐射特性及调控策略进行了系统总结,并简要介绍其代表性红外应用,重点讨论MXene在这些应用中的贡献和作用机制,包括红外识别/伪装、表面等离激元、光热转换、红外光电探测等.最后,对MXene红外功能应用的未来发展方向进行了展望.
Abstract
MXene is a large family of two-dimensional transition metal carbides,nitrides or carbonitrides.Its characteristics(various compositions,two-dimensional atomic layer structures,metallic electrical conduction,active surfaces,etc.)render MXene unique interactions with electromagnetic waves at different frequencies(visible light,infrared,terahertz,microwave,etc.),deriving a variety of electromagnetic functional applications.In the infrared range,MXene has a wide range of infrared radiation properties,and its active surface endows tunable infrared absorption.These features have attracted researchers'interest in exploring infrared properties of MXene and the corresponding applications in recent years.In this perspective,the intrinsic infrared characteristics and manipulation strategies of different MXenes are systematically summarized,and the research progress of representative infrared applications are briefly introduced,including infrared identification/camouflage,surface plasmon,photothermal conversion,and infrared photodetection.Particularly,the contribution and mechanism of MXene in these applications are discussed.Finally,the outlook for infrared functional applications with MXenes is proposed.
