| titleOfInvention | Preparation method of wave-absorbing material |
| abstract | The invention discloses a preparation method of a wave-absorbing material. The preparation method comprises the steps: mixing 60-80% of ferrite and 20-40% of nanosilver-graphene according to weight percentage, and carrying out ball milling for 2-3h until the particle size of a mixture is smaller than or equal to 2mu m to obtain the wave-absorbing material. According to the invention, nanosilver powder is loaded on a graphene carrier through an in-situ synthesis method, so that the problem of local agglomeration among nanosilver particles is solved; and meanwhile, the nanosilver powder and the graphene have excellent conductivity and heat conducting property, and the nanosilver-graphene can generate eddy current loss and the magnetic conducting ferrite can generate magnetic loss under the action of electromagnetic waves, so that the wave-absorbing effect of the wave-absorbing material can be greatly improved through compounding both the nanosilver and the graphene. |
