Sunlight‐Induced Photo‐Thermochromic Supramolecular Nanocomposite Hydrogel Film for Energy‐Saving Smart Window

An ideal energy‐saving smart window can not only provide a comfortable indoor temperature to avoid energy consumption of air‐conditioning but also require low energy consumption for the material itself. However, current studies on smart windows either need extra consumption of electric and heat energy for switching or still face some challenges such as high indoor temperature and low durability. Herein, a supramolecular nanocomposite hydrogel...
