Question

Hi all. What kind of substance is thermochromic paint made of?​

Answer 1

Answer:

Thermochromic paints use liquid crystals or leuco dye technology. After absorbing a certain amount of light or heat, the crystallic or molecular structure of the pigment reversibly changes in such a way that it absorbs and emits light at a different wavelength than at lower temperatures.

Thermochromics Materials

Thermochromic materials change reversibly their color by a temperature change. Color transition is due to a change in crystalline phase and structure. Thermochromic materials are generally organic leuco-dye mixtures, composed by the color former, the color developer, and the solvent.
