| titleOfInvention | Graphene/ferroferric oxide/copper silicate composite powder and preparation and application thereof |
| abstract | The invention provides graphene/ferroferric oxide/copper silicate composite powder with a hierarchical heterogeneous nano structure on the surface, a preparation method and application thereof, wherein the composite powder comprises a core formed by sheet graphene, an intermediate layer formed by ferroferric oxide nanospheres loaded on the core and a shell formed by needle-shaped nano copper silicate; the needle-shaped nano copper silicate is vertically arranged on the surface of the ferroferric oxide nano ball in an array form; the graphene-based hierarchical heterogeneous composite micro powder prepared by the method has the advantages of large length-diameter ratio, mesoporous structure and large specific surface area; the composite material has the characteristics of strong wave-absorbing performance, wide absorption frequency band, lightness and thinness, can keep larger electromagnetic wave shielding efficiency in a wider frequency range, and is expected to be greatly applied to the fields of electromagnetic shielding and the like. |
