Exploring Diverse Applications of Photochromic Materials

Organic photochromic materials are a new type of functional materials, which can quickly change from colorless or light color to red, green, blue, purple and other colors under sunlight or other light sources, and can return to their original state after irradiation or light protection with another light source, and can be repeatedly reversed.

Subsequently, photochromic pigment has been successively applied in clothing, decoration, ink, coating, plastic and other fields to produce color-changing clothing, color-changing sandals, color-changing glasses, etc.; It has also been successfully developed in military concealment camouflage materials, and the application of color-changing materials such as chameleon camouflage uniforms has become increasingly mature.

The five major directions of photochromic material application are:  

1. People's livelihood application field

2. Optical information storage material

3. Photografic film and holographic photographic materials 

4. Anti-counterfeiting application

5. Military application
