▎ 摘　　要

NOVELTY - Preparation of high-energy composite material copper ferrite/graphene oxide/aluminum comprises adding graphene oxide suspension to aluminum powder suspension, mixing to obtain first mixed solution, adding graphene oxide suspension to copper iron oxide suspension, mixing to obtain second mixed solution, mixing mixed liquids, centrifuging, washing, and drying. USE - The method is used for preparing high-energy composite material copper ferrite/graphene oxide/aluminum as nano thermite and thermal decomposition catalyst (all claimed). ADVANTAGE - The composite material has metal composite oxides and metal fuels, can undergo a sustained and intense redox reaction, releases huge energy, can be used as combustion propellant for solid propellants, and has catalytic effect on thermal decomposition of energetic materials, steady-state combustion effect, low stress index, simple synthesis method, and good environment protecting effect.
