The color-changing mug adopts heat-sensitive thermochromic ink, which is also called “reversible thermochromic ink” because of its reversible discoloration process. When the temperature rises, the bottom layer is displayed.
There is a special microcapsule color-changing material layer on the cup pattern. After hot water is added, the microcapsule structure changes physically from the dark state when it is cold to transparent, so that the bottom image under the cup is revealed. During the cooling process of the cup, the microcapsule changes from a transparent state when it is hot to a dark state when it is cold, so that the transparent pattern appears dark again, and the bottom image of the cup is hidden again.
This color-changing mug has an extra layer of temperature-sensitive coating made of heat-sensitive material than ordinary mugs. Thermosensitive material is also called thermochromic material, its color will change from colored to colorless, or from colorless to colored, or from one color to another. Common thermochromic materials are composed of electron donors, electron acceptors and solvents. The color developer receives the electrons provided by the color reagent to produce a color reaction, and the solvent determines the color change temperature of the material. Color developing agents include triarylmethane phenols and fluoran compounds, etc. The color developing agents are mainly phenolic hydroxyl compounds and their derivatives, and most of the solvents are alcohols.
When the temperature rises, the electrons in the atom are transferred, causing the molecular structure of the organic substance to change, thereby realizing the change of color. This reaction is reversible. When it is restored to the original temperature, the structure of the material molecule also returns to its original state, and its color returns to its original color.
The color-changing mug is the use of scientific power to serve people’s daily lives. Although the color-changing function is simple, it really gives us convenience. With the improvement of printing technology, I also designed the pattern of the mug by myself, which can be Xinyi’s literature and art, pictures, or photos of family and lovers. The combination of practicality and personalization makes color-changing mugs very popular.
