摘　　要：为了研究石墨烯的红外消光性能,采用氧化还原法制备了石墨烯,并通过扫描电镜图像、X射线衍射图谱确认了石墨烯的结构;利用烟幕箱实验和溴化钾压片法,测试了石墨烯的红外消光性能,并在同等条件下与石墨、碳纤维的消光性能进行了比较。结果表明:石墨烯在远红外波段的红外消光性能非常优异,对于8~14μm远红外波段,其平均质量消光系数约为2.10 m^(2)/g,是同等条件下石墨平均质量消光系数的2.39倍,碳纤维的3.56倍,比传统的碳材料烟幕具有更好的红外干扰能力;溴化钾压片测试也表明,石墨烯在中远红外波段均表现出非常好的红外消光能力,优于传统碳材料烟幕。In order to investigate the infrared extinction properties of graphene, graphene was prepared by redox method. The structure of graphene was also confirmed by scanning electron microscope images and X-ray diffraction mapping. The infrared extinction properties of graphene were tested using the smoke box test and potassium bromide compression method, and compared with those of graphite and carbon fibres under the same conditions. The results show that the infrared extinction performance of graphene in the far infrared band is excellent. For the 8-14 μm far infrared band, its average mass extinction coefficient is approximately 2.10 m^(2)/g,which is 2.39 times of that of the the average mass extinction coefficient of graphite and 3.56 times that of carbon fiber under the same conditions, providing better infrared interference than conventional carbon material smoke screens. Potassium bromide press tests also show that graphene exhibits very good infrared extinction in both mid and far infrared bands, outperforming traditional carbon material smoke screens.
