The present invention discloses a two-dimensional nanomaterial dispersant, a preparation method of a two-dimensional nanomaterial by liquid phase exfoliation, and use thereof. The present invention utilizes a readily synthesizable and inexpensive oligoaniline, oligoaniline derivative, polyaniline conducting polymer or the like as a dispersant of a two-dimensional nanomaterial, such as a boron nitride nanosheet or a molybdenum disulfide nanosheet, simply mixes the dispersant with boron nitride or molybdenum disulfide in a dispersion medium, such as water, an organic solvent, or a polymer resin, and can significantly improve dispersity and dispersion stability of the two-dimensional nanomaterial in the dispersion medium by a physical interaction therebetween; and can also obtain the two-dimensional nanomaterial in the dispersant by a simple liquid phase exfoliation method, which is an environment friendly and efficient process with simple operations without impairing the physical structure and chemical properties of the two-dimensional nanomaterial, and facilitates large-scale implementation.
