NOVELTY - A graphene/three-dimensional flower-shaped bismuth ferrite composite wave absorbing material is prepared by taking 25:(3-6) mass ratio of bismuth ferrite powder and graphene oxide in erosion solvent, stirring, ultrasonicating, pumping protection atmosphere, heating and stirring, adding reducing agent and complexing agent, reacting for 40-50 minutes, and cooling. USE - Method for preparing graphene/three-dimensional flower-shaped bismuth ferrite composite wave absorbing material. ADVANTAGE - The method is simple, energy efficient, continuous and easy. The product has uniform grain and has improved electromagnetic wave absorbing performance.
