| titleOfInvention | Preparation method of ferroferric oxide/copper sulfide composite electromagnetic shielding flexible membrane |
| abstract | The invention relates to the technical field of functional material preparation, in particular to a preparation method of a ferroferric oxide/copper sulfide composite electromagnetic shielding flexible membrane. Firstly, mixing a multi-walled carbon nanotube, a carboxyl nitrile rubber emulsion and a polyaziridine cross-linking agent solution, immersing the mixture into a solution containing copper sulfate for curing after film coating, adding a sodium thiosulfate aqueous solution into the copper sulfate solution after forming, heating, and reacting by adopting a chemical bath method to generate copper sulfide, thereby finally obtaining the multi-walled carbon nanotube/copper sulfide composite electromagnetic shielding film. The copper sulfate prepared by the method not only grows on the surface of the nitrile rubber, but also grows and polymerizes in the nitrile rubber, so that the formed copper sulfate can cover the surface of a nitrile rubber matrix membrane and also penetrates into the membrane, the effective absorption of copper sulfide is really completed, and the composite material has excellent electromagnetic shielding performance. |
