[0021] The morphology was characterized by a Quanta600 scanning electron microscope from Quantachrome Corporation, USA.

[0022] Synthesis of Graphene-Schiff Base Metal Complexes

[0023] (1) Synthesis of Aminated Graphene:

[0024] Put the dispersed graphene oxide ethanol dispersion in a three-necked flask, add an appropriate amount of N-aminoethyl-γ-aminopropyltrimethoxysilane ethanol solution dropwise, react at 78°C for 2 hours, and cool to room temperature after the reaction , collected by centrifugation and washed with ethanol to obtain aminated graphene. Wherein, the mass ratio of N-aminoethyl-γ-aminopropyltrimethoxysilane to graphene oxide is 15.

[0025] (2) Synthesis of graphene-Schiff base complexes:

[0026] Put the aminated graphene ethanol dispersion synthesized in step (1) in a three-necked flask, add an appropriate amount of salicylaldehyde ethanol solution dropwise, react at 78°C for 3h, cool to room temperature after the reaction, collect by centrifugation ...

Abstract

The invention discloses a graphene-Schiff base metal complex. The structural formula of the graphene-Schiff base metal complex is shown as I, and M represents catalytically active metal copper, cobaltor magnesium. The synthesis process comprises the following steps: (1) synthesizing aminated graphene from N-aminoethyl-gamma-aminopropyltrimethoxysilane modified graphene oxide; (2) reacting the aminated graphene with salicylaldehyde to synthesize a graphene-Schiff base complex; and (3) respectively reacting the graphene-Schiff base complex with copper nitrate, cobalt nitrate and a magnesium nitrate aqueous solution to synthesize the graphene-Schiff base metal complex. The graphene-Schiff base metal complex synthesized by the method can effectively improve the combustion rate of a modified double-base propellant containing octogen (HMX), and is an effective combustion catalyst of the modified double-base propellant.

Description

technical field [0001] The invention relates to a graphene-Schiff base metal complex and a synthesis method thereof. The complex can effectively increase the burning rate of a modified double-base propellant and can be used as a combustion catalyst for a solid propellant. Background technique [0002] Solid propellants are widely used in tactical missiles and rockets, and their comprehensive performance is directly related to the precision strike, high-energy damage and survivability of modern weaponry systems. By adding Octogen (HMX), RDX and Hexanitrohexaazaisowurtzitane (CL-20), the energy characteristics of the propellant can be effectively improved to meet the long-range requirements of modern tactical missiles and rocket weapons And the need for quick penetration. [0003] However, the increase of solid content will reduce the burning rate of the modified double-base propellant. By using the lead-copper-carbon composite catalyst system, the burning rate of the modifie...
