Hybrid thermochromic material [PDF]

, 2019
Vanadium dioxide (VO2) is a key material for thermochromic applications, which has a great potential to respond to the environmental temperature changing due to metal-to-insulator (MIT) transition. Temperature response hydrogel is one of the organic thermochromic materials, which reversibly changes between a transparent and translucent state depending ...
