Scalable and Healable Gradient Textiles for Multi‑Scenario Radiative Cooling via Bicomponent Blow Spinning (IMAGE)
Caption
- An ultra-flexible and gradient-structured textile is fabricated through bicomponent blow spinning, enabling the scalable production and in situ healing of the textile.
- The gradient in fiber diameter of this textile creates a hierarchically porous structure in the region exposed to sunlight, resulting in a solar reflectivity of 98.7% on its outer surface.
- The gradient in the chemical composition of this textile exhibits asymmetric spectral selectivity, wherein the outer surface offers high mid-infrared emissivity while the inner surface enables efficient radiative heat exchange.
- The gradient textile demonstrates multi-scenario radiative cooling capabilities, enabling simultaneous cooling for unheated and self-heated outdoor objects.
