Fig. 5: The correlation between solar reflectance of the porous film and the mechanical strength of the polymer matrix.
From: Humidity-tolerant porous polymer coating for passive daytime radiative cooling
The solar reflectance (a) and corresponding spectral reflectance (b) of porous polymer coating (PPC) and fumed silica added porous polymer coating (FSPPC) dried at a mid-drying-humidity (44–46% RH) depending on the fumed silica content. Compressive modulus measured by two independent experiments (c) and stress-strain curve (d) of non-porous polymer matrix (PC) and fumed silica added non-porous polymer matrix (FSPC) depending on the fumed silica content. The error bars represent standard deviation of three independent measurements for each sample. Source data are provided as a Source Data file.
