Materials that change color reversibly with temperature and light.

I have gathered materials that change color with temperature and light, and return to their original color when the temperature and light are restored.

1. Temperature-sensitive liquid material that changes color When mixed with a transparent liquid, it becomes cloudy depending on the temperature, allowing three-dimensional observation of temperature changes. The clouding temperature can be adjusted between approximately 30°C and 100°C. <Application examples> - Science teaching materials for convection observation - Visualization applications for heat transfer https://www.ipros.jp/product/detail/2000711146 2. Temperature-sensitive solid material that changes color The color tone changes reversibly according to the external environmental temperature. The color tone can be adjusted. <Application examples> - High-temperature warning paint for plant piping - Overheat warning for motors, etc. - High-temperature warning for cooking utensils, etc. https://www.ipros.jp/product/detail/2000722254 3. Transparent film that changes to a deep blue under light Once colored, it retains the color for a long time. It can be used for photosensitive materials such as blueprints. The fading time can be adjusted. <Application examples> - Film for smart windows (applied to windows to control indoor brightness) - Rewritable paper (prints and copies with light, returns to transparent after a few hours) https://www.ipros.jp/product/detail/2000710310
