MIR emissive radiative cooling textiles. a) Integrated hemispherical reflectance and emissivity spectra of a comet moth cocoon fiber from the visible to the MIR. b) SEM images of a regenerated silk fiber cross‐section containing a high density of voids. Reproduced with permission.[ 75 ] Copyright 2018, Springer Nature. c) Schematic of facile one‐step electrospinning process for preparing PVDF‐HFP fabric consisting of nanosphere structures and hierarchically porous fibers. d) Schematic illustration of the working principle of designing the rough convex nanosphere and porous structure scattering the sunlight to enhance reflectance and the intrinsic characteristics radiating heat in the long‐wave infrared. e) Digital pictures and thermal images of three identical car models at different states, respectively. Reproduced with permission.[ 76 ] Copyright 2023, Elsevier. f) Schematic of a metafabric for radiative cooling. g) The fabrication process of the metafabric. h) Temperature tracking for skin under different fabrics in direct sunlight. The insets show photographs and thermal images of the volunteer wearing a homemade vest. Reproduced with permission.[ 78 ] Copyright 2021, The American Association for the Advancement of Science.
