How materials change colour when heating/cooling | Thermochromism |Smart Materials | Part 7
This video is the continuation of Smart Materials Series.
In this video, I have shown the heat stimuli-responsive smart materials and its application in medicine, banknote security, paintings, cosmetics, toys, etc.
Thermochromism:
Thermochromism is the property of substances to change colour due to a change in temperature. A mood ring is an excellent example of this phenomenon, but thermochromism also has more practical uses, such as baby bottles which change to a different colour when cool enough to drink, or kettles which change when water is at or near boiling point. Thermochromism is one of several types of chromism.
Watch the video up to the end.
