摘要： Paint compositions and paint coatings for radiative cooling, as well as related methods of manufacturing and use of such paint compositions. A composition for paint to be used in radiative cooling, in a wet coating phase, includes nanoplatelets of hexagonal boron nitride, an acrylic binder, and a solvent. A coating of a dried paint on a surface to be cooled by radiative cooling includes nanoplatelets of hexagonal boron nitride and an acrylic binder. A method of manufacturing the composition for paint in the wet paint phase includes forming a first mixture by adding the nanoplatelets of hexagonal boron nitride to the solvent, uniformly distributing the nanoplatelets in the first mixture, and forming a second mixture by adding the acrylic binder to the first mixture.
