Abstract

The invention discloses a preparation method of a platy nanometer material. The method includes the steps of dispersing micro powder materials of a layer-shaped crystal structure in a mixed solution of hydrochloric acid and nitration, and conducting heating and ultrasonic processing on the mixed solution to obtain the platy nanometer material. The method has the advantages that the method is simple, raw materials can be easily obtained, efficiency is high, yield is high, and the method is suitable for mass production. The thickness of the obtained platy nanometer material is less than 20 nanometers, and dispersibility is high. The method can be suitable for wide application in the field of nanometer material preparation.

Description

Technical field [0001] The invention relates to the field of preparation of sheet-like nano materials, in particular to a sheet-like nano material and a preparation method thereof. Background technique [0002] Graphite, MoS 2 , WS 2 , MoSe 2 , WSe 2 , BN and other materials have a special layered crystal structure. When its size is nanometer scale, especially when the thickness is a single atomic layer or several layers, it exhibits different physical and chemical properties from bulk materials. It has been proven to be modified Electrodes, energy storage batteries, solar cells, conductive films, composite coatings and other fields have potential applications. The main obstacle that plagues the large-scale application of flake nanometers is the large-scale production and preparation of materials. After more than ten years of rapid development, mechanical lift-off methods, chemical vapor deposition methods, epitaxial growth methods, electrochemical methods, and arc methods have b...
