Fig. 1: Optical properties of porous polymer coating (PPC) and fumed silica added porous polymer coating (FSPPC) depending on the drying-humidity.
From: Humidity-tolerant porous polymer coating for passive daytime radiative cooling
Measured spectral reflectance of PPC (a) and FSPPC (b) dried at various relative humidity. The normalized ASTM G173-03 solar spectrum and the transmittance at atmospheric window are depicted at the top of the graph. c Calculated solar reflectance (Rsolar) weighted using the ASTM G173-03 solar spectrum. d Calculated figure of merit for PPC and FSPPC dried at different relative humidity. The error bars represent standard deviation of three independent measurements. Source data are provided as a Source Data file.
