Protein-based carbon/magnetic Fe Co nanoparticle composite wave-absorbing agent and preparation method and application thereof

The invention provides a protein-based carbon/magnetic Fe Co nanoparticle composite wave-absorbing agent and a preparation method and application thereof, and belongs to the technical field of wave-absorbing materials. The preparation method of the protein-based carbon/magnetic Fe Co nanoparticle composite wave-absorbing agent comprises the following steps: 1) mixing water, ferric chloride hexahydrate, ferrous chloride tetrahydrate and cobalt chloride hexahydrate, and reacting for 1-2 h at the temperature of 70-100 DEG C to prepare magnetic nanoparticles; 2) mixing the magnetic nanoparticles with egg white liquid, and curing to obtain a protein-magnetic nanoparticle compound; 3) carbonizing the protein-magnetic nanoparticle compound obtained in the step 2) to obtain the protein-based carbon/magnetic Fe Co nanoparticle composite wave-absorbing agent. The material prepared by using the composite wave-absorbing agent has strong wave-absorbing performance, meanwhile has the characteristicsof wide wave-absorbing f
