| titleOfInvention | A Fe/Fe4N/Fe3O4-rGO nanomaterial with high electromagnetic wave absorption performance, preparation method and application |
| abstract | The invention provides a Fe/Fe 4 N/Fe 3 O 4 -rGO nanomaterial with high electromagnetic wave absorption performance, a preparation method and application. In the present invention, Fe 3 O 4 nanoparticles are first prepared by a co-precipitation method, then dispersed in an aqueous dispersion of graphene oxide (GO), soaked in an aqueous solution of hypophosphorous acid and urea, and then freeze-dried and calcined at high temperature to obtain Fe/ Fe 4 N/Fe 3 O 4 ‑rGO multi-component hybrid nanomaterials. The method of the invention has the advantages of reasonable design, simple process, low cost of synthetic raw materials, safety and environmental protection; the obtained nanomaterial has a controllable morphology and uniform size distribution; it is applied to electromagnetic wave absorbing materials, and has high electromagnetic wave absorption performance in the low frequency band and wide wave absorption at the same time. It has excellent effects such as frequency band, and meets the comprehensive requirements of "thin", "broad", "light" and "strong" for modern absorbing materials, and has a wide application prospect. |
