Principle of cherry blossom color-changing mask

The principle of cherry blossom color-changing mask is temperature-sensitive color change. Thermochromic pigments are prepared by electron transfer organic compound system. Electron transfer organic compounds are a kind of organic chromonic system with special chemical structure. At a specific temperature, the molecular structure of organic matter changes due to electron transfer, thus realizing color transformation. This color-changing substance is not only bright in color, but also can realize the color change from colored = = colorless state, which is not available in heavy metal double salt complexes and liquid crystal reversible temperature-sensitive color-changing substances.
