Radiative cooling has attracted tremendous interest as it can tackle global warming by saving energy consumption in heating, ventilation, and air conditioning (HVAC) buildings. Polymer materials play an important role radiative owing to their high infrared emissivity. Along this line, numerous studies on optically optimized geometries were carried out enhance the selective wavelength absorption for emissivity; however, polymer material itself relatively was not investigated enough. Herein, we investigate radiation (IR) coefficient of various types, introduce a new concept radiative-cooling composites. By dispersing IR scattering medium matrix, be effectively scattered attenuated matrix. Indium tin oxide utilized cellulose acetate matrix report. The window film made with composite showed effective performance outdoor thermal evaluation. This opens venue endow enhanced property regardless types.
