Study on the multifunctional sequential structure film of perspective/shading/temperature control/infrared stealth
To solve the spectral demand and material design conflicts of multifunctional coupling and integration of opti-cal materials,a collaborative design method based on[TiAlN/Ag]2/TiAlN sequential structure film for visible transmis-sion induction and infrared radiation suppression is proposed,interpreting the new principles and mechanisms of multi-functional coupling of sequential structure film materials.Meanwhile,its optical compatibility performance is character-ized.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 con-trol,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.
