Sustainable all-silk textiles for personal thermal management (opens in new tab)

Hierarchically structured synthetic textiles incorporating pores or nanoparticles have demonstrated considerable promise for daytime radiative cooling. However, their widespread adoption is constrained by substantial risks to environmental and human health, including microplastic shedding and nanoparticle toxicity. Here we report an all-silk nanotextile (SilkNT) that delivers high-performance radiative cooling while remaining entirely free of synthetic polymers and toxic additives. Fabricated...
