Embodiment Construction

[0017] The present invention will be further described below by non-limiting embodiment:

[0018] 1. In the pass N 2 Under gas conditions, 20 parts by volume of 0.5mol / L n-butyllithium n-hexane solution and 1.6 parts by mass of molybdenum disulfide were stirred and reacted in a three-necked flask for 48 hours. 30 parts by volume of distilled water, and ultrasonically oscillated for 1 hour to obtain a single-layer molybdenum disulfide suspension, measure 50 parts by volume of the single-layer molybdenum disulfide suspension, and mix 30 parts by volume of ammonium chloride solution with a mass concentration of 20% under the condition of stirring Add it into the suspension under low temperature, stir and react at room temperature for 6 hours, filter after standing, wash with water, and dry in vacuum at 60°C for 24 hours to obtain (NH 4 + ) 2.9 MoS 2 intercalation compound.

[0019] 2. In the pass N 2 Under gas conditions, 100 parts by volume of 8.6mol / L n-butyllithium n-hex...

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 [0001] 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 [0002] 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 ...
