“…When 15% colored filler and 0.5% CB were added, the infrared emissivity of the fabric was 0.714. Liang et al 109 prepared four kinds of low infrared emissivity color coatings with polyurethane as the binder, aluminum as the and nanocolored pigments (CB, phthalocyanine blue, phthalocyanine green paste) as the coating. The effects of pigments on the color, surface gloss, and infrared emissivity of composite coatings were systematically studied.…”

With the rapid development of infrared detection and tracking technology, the combat concealment and viability of various military targets are seriously threatened, and the demand for military infrared camouflage is increasingly urgent. Individual combatants, as small moving targets, have the characteristics of small size, strong mobility, complex and changeable background, etc. Their infrared camouflage is more flexible and accurate than the equipment and engineering camouflage. The infrared camouflage textile material is soft and portable, which is the main embodiment of the infrared camouflage technology for individual soldiers. It can be used for infrared camouflage clothing, military tents, sleeping bags, and other equipment. Its research and development have been highly valued by many countries. In this article, details of the working principle, preparation methods, and recent research progress of flexible infrared camouflage textile materials are summarized. First of all, from the military application of infrared technology and the principle of infrared camouflage, the development status of infrared camouflage textile materials is summarized, and the research results of near-infrared and thermal infrared camouflage textile materials are introduced. Secondly, the camouflage conditions and research directions of new multi-band recombination and adaptive infrared camouflage textile materials are discussed. Finally, the challenges and opportunities of the future development of infrared camouflage textile materials, especially adaptive infrared camouflage textile materials, are considered.

“…However, temperature control is too difficult because this method requires additional cooling and heating equipment and increases the weight of the aircraft [ 8 , 9 ]. In contrast, controlling the surface emissivity is a relatively simpler method, which can be achieved through coating infrared stealth materials on objects to effectively suppress mid-far infrared signals [ 10 , 11 ]. Nowadays, infrared stealth materials, such as inorganic or metallic materials, are widely used because of their high reflectivity in the infrared band [ 12 , 13 ].…”

In order to reduce the infrared emissivity to meet the requirements of modern warfare for infrared stealth materials, we prepared the polymers containing Schiff base moieties using polyetheramine and 2,6-pyridinedicarboxaldehyde by solution polycondensation and coordinated with Ni2+, Cu2+, and Sm3+ ions to prepare organic coatings. The structure and the thermal and mechanical properties of the coatings were studied in detail. Meanwhile, the effect of the conductivity change of coordination polymers on infrared emissivity was studied systematically. The results showed the polymer coordinated with Sm3+ ions had the lowest energy band gap, which was 2.99 eV, and the best electrical conductivity of 3.54 × 10−4 S/cm compared with Ni2+ and Cu2+ coordination polymers. The infrared emissivity was the lowest in the 2–22 μm infrared waveband range, which reached 0.58, suggesting the polymers containing Schiff base moieties and their coordination polymers may have a great potential to be applied as infrared stealth materials in military applications.

“…In recent years, many researchers have conducted extensive work on infrared thermal stealth coatings. Liang et al [3] studied the preparation and characterization of low infrared emissive color coatings based on nanometer pigment. Ji et al [4] studied the vanadium dioxide nanopowders with tunable emissivity for adaptive infrared camouflage in both thermal atmospheric windows.…”

An aluminum/waterborne acrylic coating was developed by orthogonal experiments, and the gloss, emissivity, chromatic distortion, hardness, adhesion, impact resistance, and corrosion resistance of the coatings were examined. The results showed that the effect of drying time on the infrared emissivity of coatings was more significant than that of the Al powder concentration and nano-silica slurry. When the drying time was prolonged from 0.5 to 6.0 min, the gloss of the coating decreased slowly and the gloss remained low. The infrared emissivity first decreased and then increased. The infrared emissivity of coatings dried for 2.0 min was better. The L' value gradually decreased and showed a small change of range. With the increasing of the drying time, the hardness of the coating gradually decreased and was the highest at 0.5-2.0 min. The drying time had no effect on the adhesion level. The impact resistance of the coating was better during the drying period of 1.0-3.0 min. The corrosion resistance of the coating was better at 2.0 min. When the drying time was 2.0 min, the waterborne coating showed the better comprehensive performance. This study provides new prospects in using low infrared emissive coatings for infrared stealth and compatibility with visible light.
