  • Photonic polymer multilayers for colorimetric radiation sensing
    Patent number: 9519066
    Abstract: A radiation sensor includes a substrate and a polymer multilayer film including alternating layers of a high refractive index polymer and a low refractive index polymer. The high refractive index polymer and the low refractive index polymer each comprise repeat units derived from a photo-crosslinkable monomer. The radiation sensors are useful in preparing various articles, including wearable patches, packaging materials, labels, and window panes. Also described is a method of detecting radiation using the radiation sensors.
    Type: Grant
