| Abstract:In this study， nano-silica （SiO2） particles were loaded on the surface of cotton cellulose textiles（CT） by a spraying method to prepare radiative cooling cellulose textiles（SiO2-CT）. Nano-SiO2 could improve the surface roughness of CT and form a large number of light scattering centers， thus improving the ability of CT for broad-wide management of light. The results showed that the reflectance of prepared SiO2-CT reached 91% and 73% in the spectra of 0.5-1.1 μm and 1.1-2.5 μm， respectively， and its emissivity reached 0.97 in the mid-infrared spectra. Finally， SiO2-CT showed an excellent radiation cooling effect， which spontaneously enabled the sub-ambient temperature of ~4.5 ℃ at noon and ~6.5 ℃ at night， respectively. |
