With the continuous advancement of technology, smart windows, as a new type of building material, have gradually attracted people’s attention. Smart windows can not only regulate indoor light, but also effectively save energy and improve living comfort. Among them, photochromic function is one of the core technologies of smart windows. This article will introduce in detail the photochromic function of reactive gel catalysts in smart windows, including their working principle, product parameters, application scenarios and future development trends.
Photochromicity refers to the phenomenon that the material changes color under light conditions. This change is usually reversible, i.e. when the light disappears, the material returns to its original color. Photochromic materials are widely used in smart windows, glasses, displays and other fields.
Reactive gel catalyst is a substance that can initiate chemical reactions under light conditions. In smart windows, reactive gel catalysts realize automatic adjustment of window color by catalyzing the chemical reaction of photochromic materials. This catalyst has the characteristics of high efficiency, stability, and environmental protection, and is the key to the photochromic function of smart windows.
