DISPERSING AGENT FOR TWO-DIMENSIONAL NANOMATERIAL, METHOD FOR PREPARING TWO-DIMENSIONAL NANOMATERIAL BY MEANS OF LIQUID-PHASE EXFOLIATION, AND APPLICATION THEREOF

摘要

A dispersing agent for a two-dimensional nanomaterial, a method for preparing a two-dimensional nanomaterial by means of liquid-phase exfoliation, and application thereof. Oligoaniline, an oligoaniline derivative, a polyaniline conductive polymer, or the like that are easy to synthesize and low in costs is used as a dispersing agent for a two-dimensional nanomaterial such as a boron nitride nanosheet or a molybdenum dioxide nanosheet, and the dispersing agent is easily mixed with boron nitride, molybdenum dioxide, or the like in a dispersion medium such as water, an organic solvent, or polymer resin. By means of the physical interaction between the two, the dispersity and dispersion stability of the two-dimensional nanomaterial in the dispersion medium can be greatly improved; in addition, by using the dispersing agent, the two-dimensional nanomaterial can be obtained by using a simple liquid-phase exfoliation method. The physical structure and chemical performance of the two-dimensional nanomaterial are not damaged, the process is clean and efficient, and operations are simple, thereby facilitating scale implementation.
