Abstract

Hydrangea-like silica-alumina oxide microspheres (HSAOM), bio-inspired by Hydrangea flowers, show excellent photothermal properties, achieving 90% solar reflectance and 97% atmospheric window emissivity. With their corrugated surface and hollow structure, HSAOM facilitated multifaceted light-regulation mechanisms, demonstrating potential for radiative cooling materials.
