Preparation method of composite wave-absorbing material with core-shell structure

The invention discloses a preparation method of a composite wave-absorbing material with a core-shell structure, and relates to the field of microwave absorption. The preparation method of the wave-absorbing material comprises three steps of stirring crosslinking, hydrothermal nucleation and high-temperature carbonization. The wave-absorbing agent has the characteristics of excellent wave-absorbing performance and light weight, and after the silver nanowire core is compactly coated with carbon, the oxidation resistance and the stability are greatly enhanced, and the practicability of the wave-absorbing agent is effectively improved. The microwave absorbing material prepared by the invention is small in density, light in weight, high in absorption strength, relatively wide in effective absorption bandwidth, simple and convenient in preparation process, relatively low in cost, high in product stability and suitable for large-scale batch production. 本发明公开了一种核壳结构的复合吸波材料的制备方法，涉及微波吸收领域。该吸波材料制备方法，包括了搅拌交联、水热成核、高温碳化三个
