Abstract

The invention discloses a modified graphene-based iron complex, the structural formula of which is shown in I. Its synthesis process comprises the following steps: (1) N-aminoethyl-γ-aminopropyltrimethoxysilane modified graphene oxide synthesizes aminated graphene; (2) reacts aminated graphene with salicylaldehyde to synthesize modified (3) Modified graphene-Schiff base ligands coordinate with ferrous ions to synthesize modified graphene-based iron complexes. The modified graphene-based iron complex synthesized by the method has significant catalytic effect on the thermal decomposition of ammonium perchlorate (AP), and can be used as a combustion catalyst in AP-based composite propellants.

Description

technical field [0001] The invention relates to a modified graphene-based iron complex and a synthesis method thereof. The compound can effectively promote the thermal decomposition of ammonium perchlorate (AP), and can be used as a combustion catalyst of an AP-based composite 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. Combustion catalyst is an important part 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 been widely used due to their many excellent properties. Iron-containing catalysts can effectively promote the thermal decomposition of AP, thereby improving the combustion performance of AP-based composite propellants. At prese...
