| titleOfInvention | Yolk shell hollow ferroferric oxide @ air @ carbon nano composite wave-absorbing material and preparation method thereof |
| abstract | The invention relates to the technical field of electromagnetic wave absorption, in particular to a yolk shell hollow ferroferric oxide @ air @ carbon nano composite wave-absorbing material and a preparation method thereof, wherein the preparation method comprises the following steps: (1) SiO is coated on the surface of the hollow ferroferric oxide nano particle 2 (ii) a (2) Performing carboxylation modification on the surface; (3) growing MIL-100 (Fe) on the surface in situ; (4) calcining at high temperature in nitrogen atmosphere; (5) heating and stirring in alkali liquor to remove SiO 2 And washing and drying the layer to obtain the yolk shell hollow ferroferric oxide @ air @ carbon nano composite wave-absorbing material. The preparation method has the advantages of low cost, environmental protection, safety, no generation of any toxic and harmful substance, no secondary pollution, easy mass synthesis and industrial prospect; the yolk shell hollow ferroferric oxide @ air @ carbon nano composite wave-absorbing material prepared by the preparation method has the characteristics of thin thickness, light weight, low filling ratio, strong absorption, wide frequency band and easiness in regulation and control of wave-absorbing performance, and has wide application prospect. |
