【Abstract】 Based on the spectrum-selective-absorption of radiative cooling materials, an IR spectrum analysis approach, which is used to select the radiative cooling materials, is given. By measuring the absorption ratio, the normal emissivity and the radiative cooling effect of the materials, such as CaSO4,BaSO4, PTFE and organic silicon, it is proven that this approach is scientific and reliable.更多还原
