White Photothermal\nPoly(tetrafluoroethylene-<i>co</i>-hexafluoropropylene-<i>co</i>-vinylidene fluoride)/Zirconium\nCarbide Porous Fiber Fabrics with Waterproof, Breathable, Acid and\nAlkali Resistant, Flame Retardant, and Ul

Traditional methods for staying warm have a negative\nimpact on\noutdoor work and result in substantial resource consumption. In contrast,\nphotothermal conversion fiber fabrics utilize solar energy to regulate\nthe temperature, providing a sustainable solution for warmth. Here,\nporous poly(tetrafluoroethylene-<i>co</i>-hexafluoropropylene-<i>co</i>-vinylidene fluoride) (THV)/zirconium carbide (ZrC) fiber\nfabrics were fabricated via a one-step electrospinning process based\non water-vapor-induced phase separation using a binary solvent system\nof ethyl acetate and acetone. At a room temperature of approximately\n5 °C, the THV/ZrC fiber fabric with a ZrC content of 0.5% can\nrapidly heat up to 52.3 °C within 30 s under 80 mW/cm<sup>2</sup> illumination. The excellent photothermal properties combined with\nsuperhydrophobicity endowed it with significant deicing capabilities.\nMore importantly, the multifunctional properties, including self-cleaning,\nwaterproofing, breathability, flame retardancy, acid and alkali resistance,\nand ultraviolet (UV) protection, made the fiber fabric safe and comfortable\nto wear. Additionally, its white appearance enhances its aesthetic\nappeal.
