MXenes是二维类石墨烯材料中的新成员,具有良好的导电性、导热性和力学性能等优点。但是,其在充放电过程容易坍塌和堆叠,这对其使用寿命有很大影响。通过将导电聚合物插入MXenes片层间,有利于保持MXenes的片层状结构,而且可增加MXenes的电容量和导电速率,因此,MXenes/聚合物复合材料是一种性能优异的超级电容器电极材料。主要介绍了MXenes及其MXenes/聚合物复合材料的性能和制备,讨论了MXenes/聚合物复合材料在超级电容器的应用研究进展,并展望了复合材料在超级电容器上的研究前景。
MXenes is a new member of 2D graphene-like materials,and has the advantage for high electrical conductivity,thermal conductivity and mechanical properties.But it is prone to collapse and stack during charging and discharging in supercapacitor,which greatly affects its operating life.Insertion of conductive polymer into the lamellae of MXenes is conducive to maintaining the lamellae structure of MXenes,and increasing the capacitance and conduction rate of MXenes.Therefore,the MXenes/polymer composite is a kind of higher performance electrode material for supercapacitor.The properties and preparation of MXenes and MXenes/polymer composites were introduced,and discussed the application progress of the composite for supercapacitors.The prospect of the composite for supercapacitors was also prospected.
