Climate change has recently caused more and severe temperatures, inducing a growing demand for personal thermal management at outdoors. However, designing textiles that can achieve thermoregulation without energy consumption in severely hot cold environments remains huge challenge. Herein, hierarchically nanofibrous (HNF) textile with improved insulation radiative functions is fabricated efficient temperatures. The consists of cooling layer, an intermediate heating wherein the porous lignocellulose aerogel membrane (LCAM) as layer low conductivity (0.0366 W·m-1·K-1), ensuring less heat loss weather blocking external weather. introduction polydimethylsiloxane (PDMS) increases emissivity (90.4%) atmospheric window also endows it perfect self-cleaning performance. Solar absorptivity (80.1%) dramatically increased by adding only 0.05 wt% carbon nanotubes (CNTs) into polyacrylonitrile. An outdoor test demonstrates HNF temperature drop 7.2 °C compared white cotton environment be high 12.2 warmer than black environment. In addition, possesses excellent moisture permeability, breathability, directional perspiration performances, making promising environments.

Abstract Electromagnetic interference (EMI) shielding fabrics are crucial in addressing the increasingly serious electromagnetic pollution. To meet wearable requirements, stretchability and thermal comfortability often desired, but which still challenging. Herein, a stretchable EMI fabric is fabricated via electrospinning coupled with biaxial pre‐stretching spraying, block stacking wrinkled silver nanowire (AgNW)/Ti 3 C 2 T x MXene network coated on one side of electrospun thermoplastic polyurethane (TPU)/polydimethylsiloxane (PDMS) fabric. As expected, structure protects conductive from fracture during stretching process, so as to realize strain‐invariant electrical conductivity. Thus, exhibits performance over 40 dB when subjected 10–50% uniaxial strains or 21–125% strains. More importantly, white TPU/PDMS black AgNW/MXene enable passive radiative cooling heating, respectively. The high mid‐infrared emissivity (97.5%) solar reflectance (90%), thus reducing skin temperature by ≈4.9 °C. heating absorptivity (86.6%) photothermal effect increased ≈5 Therefore, fabirc Janus‐type dual‐mode personal management promising future products.

Abstract Personal protective equipment pays attention exclusively to external safety protection and ignores the internal thermoregulation of physiological state in association with sweating. Herein, a super‐hygroscopic calcium‐doped poly(sodium 4‐styrenesulfonate) superhydrophobic metal‐organic‐framework‐overlayed wearables (Ca‐PSS/MOF) integrated cooling wearable is proposed for special personal thermal management (PTM). Compared pristine fabric, MOF exhibit anti‐fouling antibacterial capabilities, efficiency up 99.99% 98.99% against E. coli S. aureus , respectively. More importantly, Ca‐PSS/MOF demonstrate significant heat index changes 25.5 °C by reducing relative humidity dramatically from 91.0% 60.0% temperature 36.5 31.6 during running test.

Abstract Personal thermal management textiles have garnered a lot of attention because they can efficiently preserve the body's and moisture comfort while saving energy consumption. Nonetheless, conduction cooling‐based textile research is scarce frequently encounters obstacles like overlooking through‐plane heat conduction, management, durability assurance.
