Research progress of functional modification of MXene and its applications

MXene is a novel kind of two-dimensional material with similar structure with graphene, which is composed of transition metal carbide, nitride or carbonitrides. Usually, it has excellent physical and chemical properties, such as large specific surface area, good electrical conductivity, excellent catalysis, excellent self-lubricating property, and abundant surface functional groups, thus showing broad application prospects in varied fields. In this paper, in view of easy stacking of MXene nanosheets and the poor compatibility with polymer matrix, the research progress of MXene surface functional modification was reviewed, including organic, inorganic and organic-inorga-nic hybrid modification methods. It also summarized the applications research progress of MXene in the fields of energy storage, catalysis and tribology, as well as prospected the future research direction.
