  • Infrared ray blocking multi-layered structure insulating film having thermal anisotropy
    Patent number: 9045897
    Abstract: The present invention relates to an infrared blocking multi-layered insulating film having thermal anisotropy, the film comprising an infrared absorption layer comprising at least one of perovskite oxide dispersed sol, metallic oxide dispersed sol, and ITO or ATO; a thermal resistance layer located on or above one surface of the infrared absorption layer; and an emission layer located on or above another surface of the infrared absorption layer. An infrared blocking multi-layered insulating film having thermal anisotropy according to the present invention may control heat flow, thereby generating excellent insulating effect.
