NOVELTY - The preparation of fluorinated graphene material, involves (1) mixing graphene oxide solution with hydrofluoric acid and stirring under reflux at 20-80 degrees C to obtain mixed solution, (2) hydrothermally reacting mixed system obtained in step (1) to obtain suspension, (3) removing excess hydrogen fluoride from suspension and drying. USE - Preparation of fluorinated graphene material for coating aluminum trihydride and aluminum powder (all claimed) for use in propellant applications. ADVANTAGE - The method enables preparation of fluorinated graphene material ensuring reduced sensitivity of aluminum trihydride and improved combustion efficiency of aluminum powder by simple, economical and environmentally-friendly process.
