Abstract

The invention discloses a method for self-assembling a homogeneous / heterojunction nano-film by utilizing a fluid boundary layer effect. The method comprises the following steps of: dissolving a nano-material in an ethanol solution, performing ultrasonic stripping and dispersion by using an ultrasonic crusher, continuously centrifuging to improve the uniformity, slowly dripping nano-material dispersion liquid into a glass dish filled with trichloromethane, wherein the nano-material forms a film on the surface of the absolute ethyl alcohol solution and the interface of the ethyl alcohol solution and the trichloromethane solution; and obliquely inserting a substrate wetted by distilled water into the liquid level, and slowly lifting to form a film. The method is low in cost, simple and convenient to operate and wide in application range.

Description

technical field

[0001] This research involves the technical field of preparation of two-dimensional thin film materials, specifically a method for self-assembling homogeneous / heterojunction nanomembranes by using the fluid boundary layer effect. Background technique

[0002] Two-dimensional materials have special structural arrangements and have proven promising for multifunctional applications such as electronics, optoelectronics, energy storage and conversion. It plays an important role in the development of cutting-edge technology, but a single two-dimensional material is limited to a certain extent due to the inherent characteristics of its structure and still fails to achieve the desired effect. Therefore, in order to achieve the performance improvement and breakthrough of two-dimensional materials, it is an inevitable choice to meet the needs of future equipment and systems by adjusting the two-dimensional structure or surface properties to achieve two-dimensional hete...
