NOVELTY - Preparing one-dimensional shell-nickel-cobalt oxide-reduced graphene oxide (RGO) wave-absorbing agent involves utilizing nickel chloride hexahydrate as nickel source, and hydrazine monohydrate as reducing agent, and preparing nickel nanowires by chemical reduction method. The nickel nanowires are coated with phenolic resin RF layer outside by in-situ polymerization of resorcinol and formaldehyde to obtain one-dimensional nickel-RF nano wire. Cobalt hydroxide nanosheets are grown on the surface of nickel-RF nanowire by the oil bath reflow method and annealed in air to form cobalt oxide nanosheets, followed by reacting coated phenolic resin RF with air to be removed, to obtain flower-shaped surface yolk- shell-nickel-cobalt oxide nanowires with shell structure, uniformly mixing nanowires and graphene suspension and hydrothermally reacting to obtain nickel-cobalt oxide/RGO composite materials. USE - Method for preparing one-dimensional shell-nickel-cobalt oxide-reduced graphene oxide wave-absorbing agent for absorbing electromagnetic waves, and improving communication quality between an aircraft and a base station (all claimed). ADVANTAGE - The one-dimensional shell-nickel-cobalt oxide-reduced graphene oxide wave-absorbing agent has good performance and good application prospect. In the layered structure of nickel-cobalt oxide nanowire, the internal magnetic nickel nanowire is dedicated to generating active magnetic loss, and the flower-shaped cobalt oxide nanosheet and reduced graphene oxide nanosheet support dielectric loss.
