| titleOfInvention | Preparation method of nano composite wave-absorbing material |
| abstract | The invention relates to a nano composite wave-absorbing material and a preparation method thereof, the method takes barium nitrate and ferric nitrate as raw materials, barium ferrite is prepared by a coprecipitation method, a hydrothermal method is used for synthesizing core-shell structure microspheres taking the barium ferrite as a core and manganese dioxide as a shell, then natural graphite powder is used as a raw material, concentrated sulfuric acid and potassium permanganate are used as oxidants, an improved Hummers method is adopted to prepare graphite oxide, and finally the graphite oxide and prepared microsphere samples are subjected to ultrasonic dispersion and then are subjected to a series of reduction to successfully synthesize the nano composite wave-absorbing material. The method adopted by the invention is simple and convenient, and the composite wave-absorbing material prepared by the coprecipitation method, the hydrothermal method and the improved Hummers method has high magnetic loss and good wave-absorbing performance. |
