Advances in radiative sky cooling based on the promising electrospinning

Radiative sky cooling has been extensively studied as a passive cooling technology with the advantages of nopollution and great energy-saving potential. The development of high-performance radiative cooling materials has always been a significant area of interest. Over the past few years, porous radiative cooling films via electrospinning have been widely studied around the world due to their great machinability, maturity, low cost and high cooling performance. In this review, the advances in porous radiative cooling films based on electrospinning are summarized from the aspects of material selection, structure design, cooling performance and application scenarios. The principles of material selection are provided for the development of high-performance radiative cooling films. Subsequently, the radiative cooler design and the corresponding cooling performance are further summarized to highlight the superiority of the electrospinning method. Furthermore, the applications of electrospinning-based coolers in personal thermal management, space cooling and ice/food preservation are discussed to reveal their significant application potential. Additionally, the challenges and prospects of electrospinning-based radiative coolers are further discussed with the aim of advancing the large-scale application of radiative cooling technology. This study is helpful to provide guidance for the design and application of radiative coolers based on electrospinning, as well as promote the commercialization of radiative cooling technology.
