Thermochromism is the property of substances to change color due to a change in temperature.

2023年7月30日 · Thermochromic materials change color at much lower temperatures and for very different reasons that have nothing to do with incandescence. There are two main types of materials that are widely used to produce thermochromic effects.

Thermochromic ink (also called thermochromatic ink) is a type of dye that changes color in response to a change in temperature. [1] [2] [3] It was first used in the 1970s in novelty toys like mood rings, but has found some practical uses in things such as thermometers, product packaging, and pens. [4]

2012年5月8日 · Thermochromic inks conjure their magic in different ways. Currently, there are two major categories of these inks: thermochromatic liquid crystals (TLCs) and leuco dyes. Liquid crystals are exactly what their name indicates -- a substance that has many properties of a liquid crossed with structural elements inherent to crystals.

2022年1月28日 · Thermochromic materials have been prepared via different physicochemical techniques with some of them combined to maximize the yield, stability, and efficiency of the prepared TCMs.

The meaning of THERMOCHROMISM is the phenomenon of reversible change of color of a substance with change of temperature (as the change of mercuric oxide from nearly colorless on being cooled by liquid air to red at room temperature and to black on being heated).

2023年5月19日 · Thermochromic pigments change color with temperature variations, adding a dynamic and interactive element to DIY projects. These pigments consist of microcapsules filled with dyes or pigments that react to heat, causing a change in color.

Photochromic materials change color when exposed to ultraviolet (UV) light, such as sunlight. They darken in response to UV radiation and return to their original color when the UV source is removed. On the other hand, thermochromic materials change …

Thermochromic materials are needed in “smart windows” that can intelligently control the intensity of transmitted light in response to environmental temperature. The thermochromic function refers to the change in light absorption coefficient of the materials in response to external thermal, electro-thermal, or photo-thermal stimulus.

Thermochromic dyes are materials that change color with changes in temperature and are being used in novelty products (e.g., T-shirts, logo’s, garments, etc.). Polychromic dyes are materials that change color in response to some other stimuli.
