“…Through a high-speed hot air draft transforming polymer melt streams into microfibers, melt-blown technology possesses advantages that enable the one-step production of microfibrous fabric while facilitating adjustments of structural characteristics such as porosity and pore size distribution, and it has been widely employed in the commercial production of microfibrous fabric. Furthermore, the incorporation of the blending process with the melt-blown process allows for the preparation of various composites, including thermoplastic polymers, such as polypropylene, , polyethylene, and polylactic acid, , and inorganic particles, such as ZnO, TiO 2 , SiO 2 , etc. Thus, it would be an innovative, industrial-scale, and environmentally friendly fabrication strategy, which involves carefully selecting suitable thermoplastic elastomers and highly reflective inorganic particles as well as efficiently regulating the pore structure characteristics by adjusting the process parameters during the melt-blown process, for enhancing both the radiative cooling functionality and the waterproof breathability.…”

In the face of escalating global temperatures, the demand for innovative passive cooling technologies that are both low-cost and environmentally sustainable is more critical than ever. However, traditional cooling fabrics face challenges in achieving wearing comfort while maintaining breathability and durability. Herein, a novel fluffy microfibrous fabric utilizing polyolefin-elastomer and polypropylene with embedded zinc oxide nanoparticles is fabricated through melt-blown technology. The results reveal that the prepared samples demonstrate exceptional daytime radiative cooling properties that present a 12.5 °C cooling capacity under 1083 W/m 2 solar radiation, highlighted by their ability to reflect up to 90.8% of solar radiation and their significantly enhanced thermal emissivity. Moreover, key findings include that the samples have robust mechanical strength, high elastic performance, and excellent antifouling capabilities, alongside superior cooling performance, which will provide an opportunity to explore the development of cooling garments for outdoor environments and contribute substantially to sustainable cooling solutions.
