Superhydrophobic bilayer coating for passive daytime radiative cooling.

ABSTRACT: Passive radiative cooling is an energy-free cooling method by exchanging thermal radiation with the cold universe through the transparent atmospheric window. Spectrum tailoring of the radiative cooler is the key to daytime radiative cooling in previously reported works. In addition, radiative coolers with large-scale fabrication and self-cleaning characteristics should be further developed to improve their industrial applicability. Herein, we propose a bilayer radiative cooling coating with the superhydrophobic property and a scalable process, by covering TiO₂/acrylic resin paint with a silica/poly(vinylidene fluoride-co-hexafluoropropylene) (SiO₂/P(VdF-HFP)) composite masking layer. The strong Mie scattering in TiO₂/acrylic resin paint contributes to high
