摘要
MXene作为一类全新的二维材料(金属碳氮化物的总称),因其本征的纳米层状结构、可调的比表面积、良好的亲水性、优异的导电性和力学性能,使其在可充电电池、超级电容器、光(电)催化剂、透明导电膜、电磁干扰屏蔽和传感器、原油和重金属的吸附剂以及柔性高强度复合材料等众多领域具有广阔的应用前景。近年来,利用插层限域工程制备MXene及其复合材料,是先进功能材料领域的研究热点。主要综述了近几年利用插层反应促进MXene剥离及合成MXene基复合材料的研究进展,比较了不同插层反应合成的MXene及其复合材料的优缺点;同时对于未来MXene及其复合材料领域的发展提出了展望。我们认为MXene及其复合材料的稳定性问题是当前要解决的瓶颈;相信随着人工智能和机器学习技术在材料研究领域的快速发展,MXene材料稳定性问题将会得到解决,并且更多具有良好稳定性的MXene及其复合材料将会被设计和合成出来。
MXene,a new family of two-dimensional transition metal carbides,nitrides,possesses the propertiesof intrinsic nano-layered structure,easily tunable specific surface area,excellent hydrophilic properties,highelectrical conductivity and good mechanical properties.Thus,it was potential to be employed in rechargeablebatteries,supercapacitors,optical(electric)catalysts,transparent conductive films,electromagnetic interferenceshielding and sensors,as well as crude oil and heavy metals adsorbents.Recently,MXene and its compositesfabricated by intercalation confinement engineering is a research hotspot in advanced functional materials.Inthe present paper,we reviewed the synthesis of MXene and its composites by intercalation confinementengineering,and compared their advantages and disadvantages with the different intercalation approaches.Finally,the development of MXene-based composites was also put forward.We think that the stability of MXene-based materials is the key point,which is very important in its applications.With the rapid development ofartificial intelligence and machine learning technology applications in materials discoveries,the stability ofMXene will be improved,more MXenes and its composites with good stability will be designed and synthesized.
