摘要
作为单原子厚度的碳材料,石墨烯因具有低密度、高比表面积和电子迁移率的特性,易于满足吸波材料所需的要求。目前,单一的吸波材料难以达到多波段、宽频带的吸收效果,为了拓宽其红外吸收频带,通过将氧化石墨烯与纳米γ-Al2O3复合,并采用水合肼原位还原制备石墨烯基吸波材料。利用Raman、XRD、FT-IR、EDX和SEM对复合材料的结构与形貌进行了分析,同时测试了烟幕对1.06 m激光和8～12 m波段的红外消光特性,结果表明,石墨烯基吸波材料对红外激光系统以及红外热像仪均具有一定的干扰作用。
Graphene as a one-atom-thick carbon materials, has some charming advantages for being used as a novel absorbing material, due to its exceptional properties including low density, large specific surface area and high electron mobility. At present, a single absorbing material has difficulty in achieving the effect of multiband and broadband absorption. In order to broaden its infrared absorption band, the graphene-based absorbing material is prepared via mixing graphene oxide and nanoq,-Al203 in situ using hydrazine hydrate. The Raman, XRD, FT-IR, EDX and SEM are used to research the structure and morphology of products. The infrared extinction abilities of nano-composites powder smoke screen to 1.06 lam laser and 8-12 lain IR are also measured. The experimental results indicate that graphene-based absorbing material has certain interference capability for IR laser and IR thermal imaging system.
