Photochromic polymer materials are polymers containing chromatic groups that change color when irradiated by light of a certain wavelength and then return to the original color under the action of light or heat of another wavelength.
Photochromic polymer materials have attracted widespread interest because they can be used in the manufacture of various goggles, window glass that can automatically adjust indoor light, camouflage and concealment colors for military purposes, coded information recording materials, signal displays, computer memory elements, photosensitive materials and holographic recording media.
