Thermodynamic Materials for Reflection
Are there any thermochromic materials that reflect infrared light (~9000nm) at 10C and transmit infrared light at 25C?
So I know some metal-insulators (ex VO2) have thermochromic infrared-reflective properties, but most of these are insulators at low temperatures and conductive at high temperatures. Some perovskites conduct at low temperatures and insulate at high temperatures, but I haven’t found any that show significant thermochromic properties and have a transition around 10C. Does anyone know of materials that satisfy these criteria? The temperature range doesn’t need to be exact.
