Abstract

The invention discloses a graphene-schiff base iron complex and a preparation method thereof, wherein the structural formula is shown as I. The synthesis process comprises the following steps: (1) twosilane coupling agents respectively modify graphene oxide to obtain two kinds of surface modified graphene; (2) the two kinds of surface modified graphene react with salicylaldehyde to synthesize a graphene-Schiff base ligand; (3) the graphene-schiff base ligand is coordinated with divalent iron ions to synthesize the graphene-schiff base iron complex. The graphene-schiff base iron complex synthesized by the method has a remarkable catalytic effect on that thermal decomposition of ammonium perchlorate (AP), and can be used as a combustion catalyst in an AP-based composite propellant.

Description

technical field [0001] The invention belongs to the field of solid propellants, in particular to a graphene-Schiff base iron complex and a synthesis method thereof, the compound can effectively promote the thermal decomposition of ammonium perchlorate (AP), and can be used as an AP-based composite solid propellant combustion catalyst used. 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. Combustion catalyst is an important component of solid propellant, which plays a significant role in improving the combustion performance of solid propellant. [0003] Composite solid propellants using AP as the oxidant have a wide range of applications due to their many excellent properties. Iron-based catalysts have been proven to have a good catalytic effect on the thermal decomposition of AP and...
