| titleOfInvention | Preparation method of hierarchical porous nickel-cobalt alloy-carbon composite block material with electromagnetic wave absorption performance |
| abstract | The invention discloses a preparation method of a hierarchical porous nickel-cobalt alloy-carbon composite block material with electromagnetic wave absorption performance, which comprises the following steps: uniformly mixing deionized water and glycerol, adding polyacrylic acid, fully stirring until the polyacrylic acid is completely dispersed and dissolved, adding a nickel source and a cobalt source which are used as precursors, hydrolyzing, adding a gel accelerator, and stirring; and sealing the obtained sol, performing gelation treatment, drying the obtained block gel, placing the obtained block xerogel in an inert atmosphere tube furnace, heating to 400-1000 ℃, and preserving the temperature for 100-300 min to obtain the hierarchical porous nickel-cobalt alloy-carbon composite block material. The hierarchical porous nickel-cobalt alloy-carbon composite block material prepared by the method has stable wave-absorbing performance. |
