摘要:MXene 是一种新型二维过渡金属碳化物和/或氮化物,可通过氢氟酸、改性酸、熔融氟盐或其他无氟法等
刻蚀前驱体 MAX 相中的活泼金属元素而得到。MXene 具有高比表面积、高电导率以及优异的光学、电学及力
学特性。将其引入涂层中可以赋予涂层光热转换、导电、增强、阻燃、抗菌等性能,从而拓展其在传感器、特
种防护等领域中的应用。该文首先综述了 MXene 的制备方法,包括氢氟酸刻蚀法、改性酸刻蚀法、熔融氟盐刻
蚀法、无氟刻蚀法等,并探讨了剥离作用对 MXene 的影响。然后详细介绍了 3 种提升 MXene 表面反应性、电
学性能、稳定性的改性方法,即插层改性、掺杂改性和防氧化改性,总结了其在传感器、电磁屏蔽、光热以及
其他功能涂层中的应用。最后,从 MXene 的功能性应用方面展望了其未来的研究方向和发展前景。

Abstract: MXene, a new class of 2D transition metal carbide and/or nitride, can be synthesized via etching
the active metal element in MAX phase of the precursor by hydrofluoric acid, modified acid, molten
fluoride salt or other non-fluoride methods. Introduction of MXene, which displays high specific surface
area, high conductivity, as well as excellent optical, electrical, and mechanical properties, into coating
achieves properties of photothermal conversion, conductivity, reinforcement, flame retardancy and
antibacterial activity, leading to application expansion in the fields of sensors, special protection, and so on.
Herein, preparation methods of MXene, including hydrofluoric acid etching, modified acid etching, molten
fluoride etching and fluorine-free etching, as well as the influence of exfoliation on MXene were firstly
reviewed, followed by detailed introduction of three modification methods, namely intercalation
modification, doping modification and antioxidation modification, to improve the surface reactivity,
electrical property and stability of MXene, and summarization of their applications in sensors,
electromagnetic shielding, photothermal and other functional coatings. Finally, the future research
directions and development prospects on the functional application of MXene were discussed.
