                 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.
