NOVELTY - Preparation of graphene oxide/nickel oxide composite absorbing material involves dissolving graphene oxide in water, ultrasonically dispersing, obtaining aqueous solution of graphene oxide, adding nickel acetate to the resultant product under magnetic stirring condition, dissolving, obtaining mixed solution, drying mixed solution, subjecting to pyrolysis in tube furnace, reacting, cooling to room temperature and collecting reaction product. USE - Preparation of graphene oxide/nickel oxide composite absorbing material (claimed). ADVANTAGE - The lightweight graphene oxide/nickel oxide composite absorbing material having excellent microwave absorption property, high strength and low reflection loss of -55.5 dB, is prepared by simple, economical and environmentally-friendly method.
