摘要： A porous polymer composite for daytime radiative cooling includes a porous polymer matrix comprising a thermoplastic polymer and including a plurality of pores, and selectively emitting particles dispersed in the porous polymer matrix. When exposed to solar radiation, the porous polymer composite comprises an infrared emissivity of at least about 80% in a wavelength range of 8-13 μm and/or a solar reflectivity of at least about 80% in a wavelength range of 0.3-2 μm.
