Interlayer bonded A-MXene nanosheets, films and preparation methods thereof

Abstract

The present invention discloses an interlayer-bonded A-MXene nanosheet, a film and a preparation method thereof, wherein there are bonding points or bonding segments of M-A-M between the MXene sheets of the A-MXene nanosheet, wherein the A is selected from at least one of the elements of group VIIB, VIII, IB, IIB, IIIA, IVA, VA or VIA, and the M represents a transition metal element in the MXene sheet; the steps include: reacting an initial MXene material with a simple substance of A or a compound of A at a predetermined temperature for a predetermined time to obtain a product having an accordion morphology, wherein the initial MXene material is a MXene material containing a -Cl, -Br or -I functional group; and peeling off the product having an accordion morphology. The present invention provides a new modification path for the technical problem that the MXene material containing a -Cl functional group has a high resistance.
