Bioinspired Metafabric with Dual‐Gradient Janus Design for Personal Radiative and Evaporative Cooling

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Сен. 12, 2024

Abstract Personal radiative cooling fabrics are a promising zero‐energy solution for creating cool and comfortable microclimate outdoor crowds. Despite significant progress, achieving efficient under some extreme situations, such as thermal shock intensive physical activity, remains challenge. Herein, bioinspired metafabric with dual‐gradient Janus design is reported personal evaporative cooling. The hierarchical fiber structure allows an excellent solar reflectance of 99.4% mid‐infrared emittance 0.94, inducing skin temperature drop 17.8 °C intense sunlight. Mesoporous silica nanoparticles fixed in the fibrous network can store capacity by atmospheric moisture‐absorption mild humid nighttime release moisture‐desorption hot daytime, providing additional 2.5 °C. Dual‐gradient endows outstanding sweat‐wicking effect high‐performance sweat capacity. In steady‐state evaporation tests, maximum consumption only 0.5 ml h −1 to temperature, preventing harmful excessive sweating. Additionally, also possesses favorable wearability color expansibility. Given these first‐rate features, will pave way development advanced functional fabrics.

Scalable multifunctional MOFs-textiles via diazonium chemistry

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Июнь 21, 2024

Abstract Cellulose fiber-based textiles are ubiquitous in daily life for their processability, biodegradability, and outstanding flexibility. Integrating cellulose with functional coating materials can unlock potential functionalities to engage diverse applications. Metal-organic frameworks (MOFs) ideal candidate such integration, thanks unique merits, as large specific surface area, tunable pore size, species diversity. However, achieving scalable fabrication of MOFs-textiles high mechanical durability remains challenging. Here, we report a facile strategy direct MOF growth on cotton fibers grafted via the diazonium chemistry. The as-prepared ZIF-67-Cotton textile (ZIF-67-CT) exhibits excellent ultraviolet (UV) resistance organic contamination degradation peroxymonosulfate activation. ZIF-67-CT is also used encapsulate essential oils carvacrol enable antibacterial activity against E. coli S. aureus . Additionally, by directly tethering hydrophobic molecular layer onto MOF-coated surface, superhydrophobic achieved self-cleaning, antifouling, oil-water separation performances. More importantly, reported generic applicable other MOFs materials, various large-scale multi-functional be successfully manufactured, resulting vast applications wastewater purification, fragrance industry, outdoor gears.

Advanced Electronic Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 9, 2025

Abstract Water and energy are the cornerstones of human development, with more than half world's population facing water scarcity issues. Atmospheric moisture is widely distributed around globe, rational utilization can create tremendous value. Here, sources hygroscopic materials, methods manufacturing hydrogels, properties these potential applications concluded. To make hydrogels high hydrophilicity, ultrasonic oscillation, freeze drying, spin coating be used as synthesis strategies. The main focus on characteristic parameters uptake, dehydration temperature, conductivity, mechanical stability, swelling behaviors, heat transfer coefficient. These unique features will affect performances assembles, devices, instruments. Subsequently, summarized, such harvesting splitting fuel production, dehumidification, thermal management in electronic solar evaporation, electricity production. Finally, future directions issues interest proposed to promote diverse development relational systems.
