为了解决可见光与红外兼容隐身的光学特性选择调控难题,基于TiO2/Ag/TiO2堆叠膜层结构集成诱导透射、辐射抑制等光学效应协同作用,提出一种可见光高透射与红外低辐射兼容的新型隐身材料,并开展结构特征对可见光透过率与红外反射率的影响机制研究,进而优化设计与制备高透光红外隐身薄膜结构,并对其兼容性隐身性能测试表征.研究表明,经优化设计的TiO2/Ag/TiO2结构各膜层厚度为30/18/35 nm时,石英基底样品的可见光平均透射率与中远红外平均反射率分别可达81.51%、90.78%,具备高水平的可见光透视与高温红外辐射抑制能力;柔性(C10H8O4)n(PET)基底样品的可见光平均透射率与中远红外平均反射率分别可达65.68%、84.46%,具备较好的透视度、遮阳与红外辐射抑制综合能力,并有高柔性曲面共形能力.该研究成果可为多频谱兼容光学隐身材料设计及应用提供重要的技术支撑.
High Transmittance Infrared Stealth Thin Films Based on TiO2/Ag/TiO2 Structure
To solve the problem of selecting and controlling the optical characteristics of visible and infrared compatible stealth,a new type of visible light high transmission and infrared low radiation compatible stealth material was proposed,based on the synergistic effect of optical effects such as induced transmission and radiation suppression of TiO2/Ag/TiO2 film structure integration.The mechanism of the influence of structural features on visible light transmittance and infrared reflectance was investigated,the optimization design and preparation of high transmittance infrared stealth film structures was implemented,and its compatibility stealth performance was tested and characterized.The results show that when the thickness of each film layer in the optimized TiO2/Ag/TiO2 structure is 30/18/35 nm,the average visible light transmittance and mid-far infrared reflectance of the quartz substrate sample can reach 81.51%and 90.78%,respectively,indicating high levels of visible light perspective and high-temperature infrared radiation suppression ability.The average visible light transmittance and mid-far infrared reflectance of the flexible PET substrate sample can reach 65.68%and 84.46%,respectively.It has good comprehensive capabilities in perspective,shading,and infrared radiation suppression,and has high flexible surface conformal ability.The results can provide important technical support for the design and application of multi-spectral compatible optical stealth materials.
