The dynamic interplay between environmental temperature fluctuations and human thermal comfort calls for intelligent textiles capable of adaptive heat regulation. Herein, a complementary, dynamic-responsive, and environment-adaptive metafabric (DREAM) is reported that integrates radiative cooling (RC) with phase-change-driven thermal buffering within a gradient porous architecture. This synergistic design enables closed-loop management of cooling energy through a harvest–storage–release mechanism, achieving effective thermal modulation under diurnal-nocturnal cycles. The high solar reflectivity (≈95.6%) and mid-infrared emissivity (≈95.4%) of DREAM ensure efficient radiative cooling, while embedded high-latent-heat microencapsulated phase-change materials (PCMs) actively respond to thermal loads. Moreover, the engineered gradient porosity imparts directional heat conduction and thermal asymmetry, suppressing external heat gain. Compared to conventional RC textiles, DREAM demonstrates a significantly enhanced cooling capacity (124.4 W m −2 ) and a daytime temperature drop of up to 19.6 °C, while reducing nighttime temperature fluctuations by 84%. Beyond its thermal performance, DREAM exhibits robust mechanical strength, excellent air and moisture permeability, and wash durability, making it promising for wearable and building-integrated thermal regulation. This work offers a material–structure–function co-design strategy for next-generation climate-adaptive textiles.

Incorporating passive heating structures into personal thermal management technologies could effectively mitigate the escalating energy crisis. However, current passive heating materials struggle to balance thickness and insulating capability, resulting in compromised comfort, space efficiency, and limited thermoregulatory performance. Here, a dual air-gelation strategy, is developed to directly synthesize ultrathin and self-sustainable heating metafabric with 3D dual-network structure during electrospinning. Controlling the interactions among polymer, solvent, and water enables the microphase separation of charged jets, while adjusting the distribution of carbon black nanoparticles within charged fluids to form fibrous networks composed of interlaced aerogel micro/nanofibers with heat storage capabilities. With a low thickness of 0.18 mm, the integrated metafabric exhibits exceptional thermal insulation performance (15.8 mW m −1 K −1 ), superhydrophobicity, enhanced mechanical properties, and high breathability while maintaining self-sustainable radiative heating ability (long-lasting warming of 8.8 °C). This strategy provides rich possibilities to develop advanced fibrous materials for smart textiles and thermal management.
