Abstract
A thermochromic polymeric nanocomposite includes layered double hydroxides (LDHs) and an embedded organic polymer. The thermochromic polymeric nanocomposite exhibits thermochromic activity, e.g., changes in color in response to a change in higher temperatures. The higher temperatures can range from 100° C.-150° C. or higher. As such, the thermochromic polymeric nanocomposite can be used to monitor temperature changes for materials approaching very high temperatures.
