A durable way to keep cool The fibers that make up textiles can be augmented to change how they interact with thermal radiation, but the resulting materials often are not durable. Zeng et al . developed a multilayer metafabric composed of a titanium oxide polylactic acid composite laminated with a polytetrafluoroethylene layer. This combination creates a textile that has passive radiative cooling properties with good mechanical properties and scalability. The textile can be made into clothes or car covers and keeps a person or a car much cooler than other fabrics. —BG
