Personal thermal management (PTM) materials have recently received considerable attention to improve human body comfort with potentially reduced energy consumption. Strategies include passive radiative cooling and warming. However, challenges remain for regulation of one material or structure in both harsh hot cold environments. In this work, silica aerogels derived from sodium silicate were prepared through a solvent-boiling strategy, where hydrophobization, solvent exchange, purification, ambient pressure drying (HSSA) proceeded successively spontaneously one-pot process. This strategy leads the synthesis superhydrophobic extremely low consumption without out use an ion-exchange resin surface tension solvents. Silica possess high specific area (635 m2/g), contact angle (153°), conductivity (0.049 W/m K). A layer-by-layer (LBL) including aerogel layer extra phase change was designed. The demonstrates dual-functional performance (-30 °C) (70 environments, time reach equilibrium is postponed, inner temperature LBL can be kept above 20 °C environments below 31 °C). proof-of-concept experimental setup simulate illumination sunlight also proved that inside model car protected by 28 °C, while outside 70 °C. addition, these results are well supported theoretical COMSOL simulation results. findings work not only provide eco-friendly approach synthesize but demonstrate robust PTM system

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.
