| Abstract: | An ideal insulation material has long been envisioned as one that not only minimizes heat loss but also provides additional heat. This study presents a non-woven fabric, comprising ultra-fine fibers embedded with zirconium carbide nanoparticles (ZrC NPs), prepared via solution blow spinning (SBS) and thermal crosslinking technology. Our results suggest that the fluffily-structured elastomer, fabricated using rigid polystyrene and flexible polyurethane, exhibits high porosity (96.96%), ultra-light characteristics (volume density of 47.12 mg cm−3), and effective heat retention (thermal conductivity of 23.1 mW mK−1 at −40°C). Moreover, the fabric demonstrates remarkable fracture strength (206.38 kPa), high elongation at break (34.5%), and superior elasticity even after 100 compression cycles at 40% strain. Despite the fact that introducing 12% ZrC increases the thermal conductivity of the base fabric by 6%, the NPs endow the material with an excellent photothermal conversion function. Following 10 min of exposure to visible light, the surface temperature increases to 71.5°C. Given its impressive performance, this novel non-woven fabric demonstrates significant potential for applications in the field of cold protection. |
