  • Visibly transparent broadband infrared mirror films having fluoropolymers and 7:1:1:7:1:1 layer thickness ratio
    Patent number: 11298918
    Abstract: Multilayer infrared (IR) reflecting films are provided. An optical repeating unit of the film include a plurality of optical polymeric layers arranged to reflect light by constructive and destructive interference. Optical layer A is a high refractive index polymeric layer, and optical layer B is a low refractive index isotropic polymeric layer containing fluoropolymers. The film has an average reflectance of about 50% to about 100% in a near infrared wavelength range of about 850 nm to about 1850 nm, and an average transmission of about 70% to about 90% in a visible light range.
    Type: Grant
