Abstract Outdoor electronics are simultaneously subject to constant solar radiation and instantaneous thermal shock, thus urgently requiring effective management. However, commonly adopted radiative cooling has an issue of low power phase change temperature control technology suffers from materials leakage, which cannot meet the increasing demands for outdoor electronics. To address these problems, a leakage‐proof wrapped cooler that integrates latent heat storage is proposed achieve sub‐ambient efficient thermal‐shock resistance. The designed by directly wrapping paraffin wax (PW) material (PCM) within hexagonal boron nitride/polydimethylsiloxane (h‐BN/PDMS) coating, possessing property during force shock. can average drop 4.8 °C under direct sunlight. Moreover, maximum 35.3 be achieved heater covered with when experiencing 2000 W m −2 mainly due temperature‐pinning effect PCM high conductivity h‐BN/PDMS coating. provides way protecting damage, thereby advancing passive management technologies toward practical applications.

Superhygroscopic Aerogels with Hierarchical String-Bag Structure for Effective Humidity Control

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Апрель 21, 2025

Environmental humidity regulation is crucial for diverse applications ranging from healthcare, food preservation, drug storage, to electronics protection. Herein, we employed natural cellulose as the raw material fabricate superhygroscopic aerogels with hierarchical string-bag structure effective control. The aggregation state of chains was regulated micronano materials, including nanofiber network (CNFN), dendritic microfibers (CDF), and pleated (CPF), via changing precipitation process cellulose/ionic liquid solutions. They immobilized hygroscopic salts (LiCl, CaCl2, MgSO4) form uniform featuring micrometer macropores nanometer string-bags. molecular-level distribution metal along macropore wall nanofibers, combined high hydrophilicity cellulose, enabled rapid moisture absorption environment transportation within structure. Moreover, conducive water storage. CNFN/LiCl aerogel demonstrated exceptional performance, achieving a uptake 1.36 3.14 g/g at 30% 70% RH, respectively. Such materials could rapidly effectively control environmental humidity, indicating huge potential in regulation.
