摘要：
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 m2/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. © 2023 Chinese Society of Astronautics.
