An overview of the methods of synthesis, characterization and applications of MXene as a Microwave absorber

Recent developments indicate that a large and new family of two-dimensional transition metals consisting of carbides, carbonitrides and nitrides with the general name of MXene have attracted much attention. MXenes have significant physical and chemical properties with a rich variety of basic elements. In order to effectively adjust the properties of MXenes to achieve different applications, they can be easily combined with other materials such as polymers, oxides and carbon nanotubes. Due to the fact that human daily life is full of electromagnetic wave (EM) pollution, which threatens human health, the development of advanced microwave absorbing materials has become an important issue. Two-dimensional materials such as MXene, graphene, and molybdenum disulfide (MoS2) have unique electromagnetic properties and potential applications in absorbing electromagnetic waves, shielding, and microwave waves stealth due to their special structure, excellent electrical conductivity, rich surface, and good mechanical strength. In this regard, because of having desirable structures and properties such as a special layered structure, abundant and adjustable surface active functional groups, excellent electrical conductivity, and high specific surface area MXenes are suitable candidates for absorbents. In this article, the synthesis methods and properties of MXenes are summarized first, and then their recent developments in applications related to the field of microwave absorbers, which are of great importance, have been reviewed. Finally, the challenges and bright horizons of future research in the field of new two-dimensional materials of MXenes have been presented.
