Science Alert  July 13, 2021 The metafabric developed by researchers in China uses titanium oxide-polylactic acid composite nanoparticles laminated with a thin layer of polytetrafluoroethylene (PTFE). It is designed to strongly reflect visible light (VIS), mid-infrared (MIR) and ultraviolet (UV) ranges. The wide distribution of nanoparticles, when combined with PTFE nanobeads, provides broad-spectrum scattering and reflectivity across the UV-VIS-NIR band. They tested the material in clear sky conditions measuring the temperature of the fabric in comparison to other common materials lying on a panel. Under peak solar irradiance between 11:00 and 15:00, the temperature of the metafabric was approximately 5.0°, […]
