| titleOfInvention | A flower-shaped Fe/Fe3C/Fe3O4 composite wave absorbing material and preparation method thereof |
| abstract | The invention belongs to the field of material preparation, and relates to a flower-shaped Fe/Fe 3 C/Fe 3 O 4 composite wave absorbing material and a preparation method thereof. The invention aims to solve the problems of weak dielectric loss capability, obvious Snoek effect, and narrow absorption frequency band of traditional Fe 3 O 4 wave absorbing materials. The preparation method of a flower-like Fe/Fe 3 C/Fe 3 O 4 composite wave absorbing material can alleviate the skin effect of magnetic metals and reduce the impact of other dielectric components (carbon materials, conductive polymers, etc.) on Fe 3 O 4 magnetic dilution. In the invention, the carbon dots are used as the decoration material of flower-like Fe 3 O 4 , and the flower-like Fe/Fe 3 C/Fe 3 O 4 composite material is obtained by annealing at high temperature. The introduction of magnetic metal is based on ensuring the magnetic loss characteristics of the composite material. The ability of dielectric loss is enhanced, the impedance matching is improved, the complementary advantages of the two components are realized, the integrated effect is achieved, and the absorbing performance is effectively enhanced. |
