Abstract

Atmospheric water harvesting (AWH) technology, which extracts moisture from ambient air, is a promising solution to global water shortages. Salt-based sorbents are promising for AWH due to their high water uptake capacity. However, these materials require substantial atmospheric exposure for high sorption/desorption kinetics, limiting space efficiency while also suffering from poor stability and high energy demands for water desorption. Herein, a LiCl-incorporated PHEA/PEGDA composite (LiCl-HG) was developed via 3D printing to achieve high exposure with minimal space occupation, enabling efficient moisture capture and water storage. The gyroid composite achieves a water uptake of 6.0 g g–1 under 70% relative humidity (RH), with low desorption energy (1472 kJ kg–1) and a high desorption rate (1984 × 10–6 kg m–2 s–1 at 60 °C). Leveraging its superior performance, a dry cabinet was designed that can maintain the relative humidity at 5% while reducing the energy consumption by 30%. Additionally, AWH tests for the 3D-printed composite highlighted the water production rate up to 9.06 kg kg–1 day–1. A humidifier was further developed to improve energy efficiency, cutting humidification energy use by 50%. These findings offer a promising pathway for the synthesis of materials with high efficiency in miniaturized and integrated AWH and humidification systems.

将盐结合水凝胶集成到用于大气水收集和加湿的3d打印陀螺仪中。
大气集水(AWH)技术,从周围空气中提取水分,是解决全球水资源短缺的一个很有前途的解决方案。盐基吸附剂因其高吸水能力而被广泛应用于水处理。然而,这些材料需要大量的大气暴露以获得高吸附/解吸动力学,限制了空间效率,同时也存在稳定性差和水解吸高能量需求的问题。在此,通过3D打印开发了一种含licl的PHEA/PEGDA复合材料(LiCl-HG),以最小的空间占用实现高曝光,实现高效的水分捕获和水储存。在70%相对湿度(RH)条件下,陀螺复合材料的吸水率为6.0 g g-1,解吸能低(1472 kJ kg-1),解吸速率高(60℃时为1984 × 10-6 kg m-2 s-1)。利用其优越的性能,设计了一个干燥柜,可以保持5%的相对湿度,同时减少30%的能耗。此外,3d打印复合材料的AWH测试显示,产水量高达9.06 kg kg-1 day-1。加湿器进一步开发,以提高能源效率,减少50%的加湿能源使用。这些发现为在小型化、集成化的空气净化器和加湿系统中高效合成材料提供了一条有希望的途径。
