NOVELTY - Radiative cooling system comprises 2-10 wt.% missive materials and polymer, for thermally radiating in the wavelength range from 8-13 micrometer. USE - Radiative cooling system. ADVANTAGE - None given. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a radiative cooling system, which involves: a. dispersing polymer and emissive materials in the range of 2-10% wt of polymer in a solvent to obtain a solution; b. stirring the solution for a period of about 50-60 hours at 25-30℃ or stirring the solution for a period of 8-10 hrs at 70-80℃; and c. evaporating the solvent to obtain a product.
