Color change of thermosensitive material composed of synthetic saponite and crystal violet.
A material that reversibly changes color according to the surrounding temperature! It exhibits significant color changes around 100°C.
This is about a new thermochromic material that changes color according to the external environmental temperature, featuring various characteristics. We will introduce the color change of the thermochromic material made from synthetic saponite and crystal violet. This material reversibly changes color according to the surrounding temperature, exhibiting significant color changes around 100°C. It can be processed into powder or thin film and can be applied regardless of the surface shape. Please contact us if you would like a sample. 【Features】 ■ The color of this material gradually changes slightly with the increase in temperature from room temperature, but shows significant color change around 100°C. ■ When the temperature is lowered back to room temperature, it returns to the color before the temperature increase. ■ Repeated color changes are observed on both the high-temperature and low-temperature sides of a specific temperature. ■ It can be produced through simple preparation. *For more details, please refer to the PDF document or feel free to contact us.
