With the rapid development of military optoelectronic technology, the role of stealth technology in modern combat systems is becoming more and more important, among which, stealth materials are crucial to improve stealth performance. We focus on infrared stealth materials and review the research progress of domestic and foreign infrared stealth materials from three aspects including single-band infrared stealth, multi-band compatible infrared stealth, and dynamic infrared stealth, and provide an in-depth analysis on the large-area flexible processing methods for micro-nano structures. The main problems of current infrared stealth materials are summarized and the future development trend is foreseen. In the future, to achieve high-performance stealth functions, new infrared stealth materials will further develop in the direction of high strength, large area, flexibility, and intelligence.
