Preparation method of iron-based compound / fish skin derived carbon composite wave-absorbing material

Abstract

The invention discloses a preparation method of an iron-based compound / fish skin derived carbon composite wave-absorbing material, and relates to a preparation method of a fish skin derived carbon composite wave-absorbing material. The invention aims to solve the technical problems of single energy loss mode, large packing ratio and density, narrow microwave absorption bandwidth and single function of the existing EMWA material. Prussian blue microcubes are prepared through an improved method to serve as an iron source, organic amine in fish skin is ingeniously used for providing a nitrogen source, in-situ nitridation is achieved through external thermal driving and N atoms in the fish skin, the Fe3N (at) C composite material is synthesized under the condition that ammonia gas does not need to be additionally added, and by introducing cellulose nanofibers, the composite material can be used for preparing the composite material. According to the method, the Fe3N / Fe3C-coated C composite material with the double magnetic coupling systems is produced, the method is free of pollution and capable of saving energy, carbon emission is reduced, the atom utilization rate is greatly increased, and therefore the method has the industrial production application and popularization value.
