| titleOfInvention | Preparation method of nano porous carbon coated magnetic nanoparticle compound |
| abstract | The invention provides a preparation method of a nano porous carbon coated magnetic nanoparticle compound, belonging to the technical field of composite materials. Firstly, synthesizing graphite-phase carbon nitride, mixing the graphite-phase carbon nitride with magnesium powder, then carbonizing at high temperature, and washing a product with hydrochloric acid to obtain nano porous carbon; secondly, dissolving metal salts of iron, cobalt and nickel in methanol, adding nano porous carbon, mixing and drying; and finally, calcining the mixture at high temperature to obtain the nano porous carbon coated nano particle composite wave-absorbing material. According to the invention, the magnetic nanoparticle composite wave-absorbing material is coated by the nano porous carbon by a two-step method, so that good electromagnetic wave absorption capability is shown; the preparation method is simple to operate, and the product has good electromagnetic parameters and electromagnetic wave absorption capacity. |
