The development of high efficiency and environmental protection type anti-infrared smokescreen has attracted wide attention at home and abroad. For this reason, all countries in the world actively develop low-toxic solid infrared extinction materials. Now metals, new carbon materials and anti-infrared composites are reported. In this paper, the research status of infrared extinction characteristics of solid aerosol particles is introduced. The research progress of the above-mentioned three kinds of materials is reviewed. It is pointed out that simulation study on extinction characteristics of aerosol particles, nano carbon materials and metal film composites are still the key research directions in the future. It is suggested that nano infrared absorbing materials, absorbing materials with one-way transparency and metallized biosome infrared absorbing materials should be actively focused on and explored. These materials are expected to become a new generation of anti-infrared materials in smokescreen. 63 references are attached.
