(NH4+)XMOS2 intercalation compound and its preparing method

Abstract

The invention discloses (NH4+)xMoS2 inserting compound and x is 0.2-3.0. The method includes the following steps: taking layer inserting to supramoly by using butyl lithium to gain layer inserting supramoly, making supramoly supernatant liquid, making (NH4+)xMoS2 layer inserting compound in ammonium chloride solution. The invention could be used as a good solid lubricant and could heating with alkali to gain single layer supramoly. It solves the storing problem of single layer of supramoly. It has crucial application value in mechanical, electric, aviation and spaceflight, chemical, etc.

Description

1. Technical field The invention relates to a functional material and a preparation method thereof, in particular to MoS 2 Intercalation compound and preparation method thereof, specifically a kind of (NH 4 + ) x MoS 2 Intercalation compounds and methods for their preparation. 2. Background technology Molybdenum disulfide belongs to the hexagonal crystal system and has a layered structure similar to graphite. There are strong covalent bonds in the layers and weak van der Waals forces between the layers. The layers are easy to peel off, so they have good anisotropy. Anisotropy and low friction coefficient, the use of appropriate substances can be inserted between molybdenum disulfide layers to form intercalation compounds, which can be used to prepare composite materials. S has a strong adhesion to metals, so that molybdenum disulfide can be well attached to the metal surface and always play a lubricating function, especially under high temperature, high vacuum and other...

AI Technical Summary

Problems solved by technology

In single-layer molybdenum disulfide, Mo is octahedral coordination, which is a metastable state. After a period of aging, it will gradually transform into stable triangular prism coordination. Therefore, single-layer molybdenum disulfide cannot be stored for a long time at room temperature. with use

The literature [Acta Tribology, 2003, 5(3): 192-196] reported the preparation of a monolayer molybdenum disulfide suspension, but the storage problem of the monolayer molybdenum disulfide itself has not yet been solved
