摘要

Maintaining physiological thermoregulation homeostasis under extreme cold environments is critically imperative for human survival and functionality. However, traditional thermal management textiles face multifaceted challenges including limited insulation methods, unsatisfactory thermal efficiency, and narrow applicability across complex scenarios. Herein, a well-constructed advanced fabric is fabricated via layer-by-layer (LBL) self-assembly of carbon nanotubes (CNTs) and polydopamine (PDA) with an integrated design that synergistically combines high-efficiency photothermal conversion, Joule heating, superhydrophobic self-cleaning, and UV shielding properties. The CNT-PDA hierarchical design enables broadband solar energy harvesting (97% absorbance) and high photothermal efficiency for passive thermal management through solar energy. The synergistic combination of PDA's adhesive properties and LBL self-assembly techniques facilitates the construction of the 3D conductive network of CNTs with enhanced electrical conductivity (273.96 S/m), achieving wide-range temperature modulation (ambient to 100 °C+) via low-voltage-driven Joule heating for personalized active thermal management. The dual-energy strategy combining passive and active thermal management effectively addresses diverse thermal regulation requirements for body warming in extreme cold environments, ensuring all-day performance. Furthermore, the addition of methyltrimethoxysilane (MTMS) endows the fabric with hydrophobicity (water contact angle = 147.2°) and self-cleaning capability, enhancing its reliability under the extreme conditions of rain and snow in cold environments. Moreover, advanced fabrics exhibit low transmittance (4%) in the ultraviolet spectrum, providing effective ultraviolet protection in high-altitude, cold regions where ultraviolet radiation is particularly intense. This multifunctional advanced fabric with the simple preparation technique and outstanding overall performance provides promising applications for next-generation all-day personalized thermal wearables in extreme cold environments.
