Emissivity Regulated Fabric: Achieving Self-Adaptive Radiative Cooling and Dynamic Body Radiation Manipulation.

ABSTRACT: Effective manipulation of radiative cooling power is crucial for thermal management systems. However, the potential for radiative cooling regulation through emissivity modulation in textiles remains unexplored. As a proof-of-concept, a self-adaptive radiative cooling fabric (SARCF) is presented, exhibiting high solar reflectance and variable infrared emissivity. The SARCF is created by depositing tungsten doped vanadium dioxide (W-VO₂) nanoparticles on low-emissivity (low-e) fabrics, followed by welding with nanoporous polyethylene (NanoPE). SARCF demonstrates significant solar reflectance (85.19%) and a promising emissivity contrast (Δɛ, 34.82%) for radiative cooling regulation, driven by the temperature-induced phase transition of W-VO₂.
