Solar Radiation Reflective and Infrared Radiation Emissive and Reflective Window Blinds
We disclose a window blind which includes a metamaterial film on the slats. The metamaterial film reflects solar irradiance and is infrared emissive. The metamaterial fabric may contain silicon dioxide microspheres embedded in a polymer and the polymer may be coated with a silver coating. The long edges of the slats of the blinds may be attached to a sheet of substantially transparent infrared reflective optical interference film. When the slats of the blinds are open, the infrared reflective optical interference film may reflect infrared radiation thus preventing it from passing into the adjacent room while still permitting light to enter the room. The metamaterial film may inhibit both solar and infrared radiation from heating the adjacent room. Consequently, the disclosed window blinds promote radiative cooling instead of impeding heat transmission into an adjacent room.
