The invention relates to an MXene-Ti 3 C 2 T x nanosheet film, which is formed by dispersing MXene-Ti 3 C 2 T x in a dispersion medium to form a dispersion liquid, uniformly coating the surface of a substrate, and removing the dispersion medium through annealing treatment to form a dispersion liquid. film, and then the surface of the film is subjected to ultraviolet ozone treatment to obtain a nano-sheet film. In the invention, the surface modification of the nano-sheet film is performed by ultraviolet ozone treatment to improve its work function and the hole injection capability of the film, and can be used as a hole injection layer material to be applied in the preparation of OLEDs. |
