Abstract:
Coatings configured to change between a relatively higher reflectivity state and a relatively lower reflectivity state depending at least partially upon temperature are generally disclosed. Some example coatings may include a selectively reflective layer including a plurality of microcapsules, which may include an ionic liquid and/or a surfactant within a shell. The microcapsules may have a relatively higher reflectivity when at temperatures above a cloud transition temperature and/or a relatively lower reflectivity when at temperatures below the cloud transition temperature. When at temperatures above the cloud transition temperature, the selectively reflective layer may reflect a first fraction of the incident light. When at temperatures below the cloud transition temperature, the selectively reflective layer may reflect a second fraction of the incident light. The first fraction of the incident light may be greater than the second fraction of the incident light.
