Title
(EN) METAL-FREE SOLAR-REFLECTIVE INFRARED-EMISSIVE PAINTS AND METHODS OF PRODUCING THE SAME
(FR) PEINTURES À ÉMISSION INFRAROUGE ET RÉFLEXION SOLAIRE SANS MÉTAL ET LEURS PROCÉDÉS DE PRODUCTION
Abstract
(EN) Metal-free compositions for solar-reflective infrared-emissive coatings and methods of producing the same. The paints are suitable for reducing the temperatures of objects below ambient temperatures between sunset and sunrise (nighttime) and part or full daytime (between sunrise and sunset) when such objects are subjected to direct sunlight. Such a solar-reflective infrared-emissive paint may include a particle-polymer composite containing particles in a polymeric matrix, wherein the particles are nanoparticles or microparticles, the paint does not contain a metallic component, and the paint exhibits high reflectance for the solar spectrum wavelengths of 0.3 to 3 micrometers and high emissivity for wavelengths of 8 to 13 micrometers.
(FR) L'invention concerne des compositions sans métal pour des revêtements à émission infrarouge et réflexion solaire et leurs procédés de production. Les peintures sont appropriées pour réduire les températures d'objets au-dessous des températures ambiantes entre le coucher du soleil et le lever du soleil (nuit) et durant une partie ou la totalité du jour (entre le lever du soleil et le coucher du soleil) lorsque ces objets sont soumis à une lumière solaire directe. Une telle peinture à émission infrarouge et réflexion solaire peut comprendre un composite à base de polymère particulaire contenant des particules dans une matrice polymère, les particules étant des nanoparticules ou des microparticules, la peinture ne contient aucun constituant métallique, et la peinture présente une réflectance élevée concernant les longueurs d'onde du spectre solaire de 0,3 à 3 micromètres et une émissivité élevée pour des longueurs d'onde de 8 à 13 micromètres.
