为了解决光学材料多功能耦合与集成的光谱诉求及其材料设计冲突难题,本文提出一种基于[TiAlN/Ag]^(2)/TiAlN序构复合薄膜开展可见光透射诱导与红外辐射抑制的协同设计方法,诠释序构薄膜材料多功能耦合的新原理与新机制,并对其光学兼容性能测试表征。研究表明,构筑的[TiAlN(厚度为30 nm)/Ag(厚度为15 nm)]^(2)/TiAlN(厚度为30 nm)序构复合薄膜具备带通状选择性透射与中远红外低辐射的光学特性,可较好实现透视、遮阳、低辐射控温与红外隐身多功能兼容效果,在军用车辆、绿色建筑等特种玻璃的辐射控温与红外隐身领域有应用潜力。

To solve the spectral demand and material design conflicts of multifunctional coupling and integration of optical materials,a collaborative design method based on[TiAlN/Ag]^(2)/TiAlN sequential structure film for visible transmission induction and infrared radiation suppression is proposed,interpreting the new principles and mechanisms of multifunctional coupling of sequential structure film materials.Meanwhile,its optical compatibility performance is characterized.It shows that the[TiAlN(thickness of 30 nm)/Ag(thickness of 15 nm)]^(2)/TiAlN(thickness of 30 nm)sequential composite film has the optical characteristics of band-pass selective transmission and mid-far infrared low radiation,which can better realize the multifunctional compatibility effects of perspective,shading,low radiation temperature control,and infrared stealth,and can be used in the radiation temperature control and infrared stealth application fields of special glasses such as military vehicles and green buildings.
