Thin films including nanoparticles with solar reflectance properties for building materials

摘要

Disclosed are solar-reflective building materials, including roofing articles, that include nanoparticle-containing thin films; such articles display high reflectance of near-infrared radiation and high transmission of radiation in the visible light range so as to reduce the heat island effects experienced by the articles while also maintaining an aesthetically pleasing appearance. Also disclosed are related methods of fabricating such articles.
