▎ 摘　　要

NOVELTY - Method for preparing polyethyleneimine-enhanced graphene deactivation energetic material, involves (a) dispersing the energetic material in an aqueous phase, and slowly adding the polyethyleneimine aqueous solution under stirring to obtain a first mixed liquid, where the mass ratio of the energetic material to the polyethyleneimine is 98:(0.05-1.95), (b) adding a graphene dispersion aqueous solution to the first mixed liquid to obtain a second mixed liquid under stirring conditions, where the mass ratio of polyethyleneimine to graphene is 1.95:0.05-0.05:1.95, (c) continuously stirring the second mixed solution for 2-10 hours to obtain a suspension, and (d) filtering, washing and drying the suspension to obtain the product. USE - The method is used for preparing polyethyleneimine-enhanced graphene deactivation energetic material (claimed). ADVANTAGE - The method enhances the interaction between the desensitizer and the energetic material, and reduces the mechanical sensitivity of the energetic material.
