Silver nanowire composite aerogel wave-absorbing agent and preparation method thereof

The invention discloses a silver nanowire composite aerogel wave-absorbing agent and a preparation method thereof, and relates to the field of microwave absorption. The preparation method of the wave-absorbing material comprises the four steps of silver nanowire synthesis, stirring crosslinking, freeze drying and high-temperature carbonization. The wave-absorbing agent has the characteristics of excellent wave-absorbing performance and light weight, and the silver nanowire composite aerogel is light in weight and small in density, so that the practicability of the wave-absorbing agent is effectively improved. The microwave absorbing material prepared by the invention is high in absorbing strength, relatively wide in effective absorbing bandwidth, simple and convenient in preparation process, relatively low in cost, high in product stability and suitable for large-scale batch production. 本发明公开了一种银纳米线复合气凝胶吸波剂及其制备方法，涉及微波吸收领域。该吸波材料制备方法，包括了银纳米线合成、搅拌交联、冷冻干燥、高温碳化四个步骤。该吸波剂与具有出色的吸波性能和轻质的特点，银纳米线复合气凝胶质量轻、密度小，有效的提高了该吸波剂的
