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.
Dear Ethan,
There is a similar question which were posted in the research gate forum. This could answer your question. Please see the following link

Dear Xuhua Wang ,
Thank you for your response. I read that post before posting this question. VO2 shows a strong thermochromic effect, the issue is that its an insulator at low temperatures and a conductor at high temperatures because of its Mott transition. I'm looking for the reverse process: conduction at low temperatures and insulation at high temperatures.
Thanks,
Ethan
Dear Ethan,
Thanks for the clarification of your question. It is very interesting! I doubt it would be very difficult to find a few materials to have such properties. It needs many screenings or efforts. It could be a big discovery though.
Best luck
