Abstract:
1. A composite material heat controller for an object, the composite material heat controller comprising: a base material that radiates a larger amount of heat at a high-temperature relative to that of the heat radiated at a low-temperature, the base material having a surface adapted to thermally contact a surface of said object; and a phase-change substance overlying said base material having insulation properties at the high-temperature, metallic properties at the low-temperature, radiating a larger amount of heat at the high-temperature relative to a smaller amount of heat radiated at the low-temperature, and having a high reflectivity in the thermal infrared light region at the low-temperature; wherein said phase-change substance comprises a perovskite oxide or a corundum vanadium oxide and has a thickness in the range from about one to about thirty microns.
