Abstract: The present invention relates to a metamaterial composition having excellent radiative cooling characteristics and a film prepared from same. The metamaterial of the present invention comprises a base material, aerogel particles and optical control agent, and thus can exhibit high visible light transmittance and excellent infrared emissivity even with a thin thickness. Therefore, the metamaterial of the present invention can be used as a radiative cooling film requiring transparency, and can be usefully applied to, especially, a cover window for a display.
