摘　　要：随着红外侦测技术的快速发展,提高热物体的红外伪装能力在国防领域具有重要意义。本文提出一种可见红外双波段智能伪装织物,利用纳米多孔吸湿膜红外发射率的温度自适应性,实现织物红外动态伪装;并利用红外透明的表层设计织物颜色,实现可见与红外兼容伪装。实验表明,当织物温度在22~64℃之间变化时,其红外发射率能在0.95~0.38范围内自适应调节。该织物将可见颜色与红外辐射的调控集于一片柔性布上,在可见红外兼容智能伪装技术领域具有一定的应用前景。With the development of infrared detection technology,it is important to improve the infrared camouflage capability of hot objects.Here,we presented a smart textile for visible and infrared dual camouflage.Within the textiles,the thermal emissivity of moisturized nanoporous films can adaptively response to environmental temperature variation,achieving dynamic infrared camouflage.The visible color of the smart textiles could also be designed with a color top layer of high infrared transparency,resulting in visible-infrared compatible camouflage.Experiments indicated that the infrared emissivity of the smart textiles adaptively changed in the range of 0.95~0.38 with the temperature varying from 22℃ to 64℃.With the capability of modulating the visible coloration and infrared emissivity,the smart textiles could have a potential for applications in visible and infrared dual-band camouflage.
