Molybdenum disulfide/polyferrocenyl Schiff base composite material and preparation method thereof

Abstract

The invention discloses a molybdenum disulfide / polyferrocenyl Schiff base composite material and a preparation method thereof, and relates to a composite functional material which is synthesized by compounding molybdenum disulfide and polyferrocenyl Schiff base and has multiple excellent properties such as lubricity and conductivity. The preparation method of the molybdenum disulfide / polyferrocenyl Schiff base composite material comprises the following steps: 1, preparing a lithium-intercalated molybdenum disulfide suspension; 2, preparing a polyferrocenyl Schiff base / DMF mixed solution; 3, dropwise adding the polyferrocenyl Schiff base / DMF mixed solution into the lithium-intercalated molybdenum disulfide to obtain a reaction product; and 4, carrying out separation treatment on the reaction product to obtain the molybdenum disulfide / polyferrocenyl Schiff base composite material. The preparation method has the advantages that the problems of poor compatibility and non-uniform dispersionof a traditional physical blending method are fundamentally solved, and various excellent properties such as lubricity and conductivity of the material are improved. The method is mainly used for preparing the molybdenum disulfide / polyferrocenyl Schiff base composite material.

Description

technical field [0001] The invention relates to a molybdenum disulfide / polyferrocenyl Schiff base composite material and a preparation method thereof. Background technique [0002] The two-dimensional layered transition metal chalcogenide (molybdenum disulfide) is a "sandwich" structure: two layers of sulfur atoms form a sandwich structure, a layer of molybdenum atoms is between the interlayers, and the layers are connected by van der Waals force. Based on the unique spatial structure and valence band structure of molybdenum disulfide, molybdenum disulfide nanomaterials have been widely used in many fields such as photovoltaic devices, lubricants, electrocatalysis, and hydrogen energy storage. Ferrocene has a sandwich structure and an aromatic highly electron-rich system with good thermal stability and good reactivity. This metal-organic compound is more popular among many metal-organic compounds due to its cheapness, low toxicity and easy substitution. Having attention. T...
