Problems solved by technology

Although studies have demonstrated the feasibility of these materials for air water harvesting, the high synthesis cost and complicated preparation process limit the further application of these hygroscopic materials.
[0004] The synthesis of these air water-collecting materials involves various expensive chemical substances, such as MOF precursors, polymer hydrogel monomers, etc., and fine technical processes such as centrifugation, ultrasound, and freeze-drying are applied in the preparation process. Significantly increases the overall cost of materials, hindering their application
In addition, in arid and remote areas, most people cannot afford such a high cost and the need for air-water harvesting materials is even more urgent

Description

technical field [0001] The invention belongs to the field of air water and water collection materials and humidity power generation materials, in particular to a multifunctional hygroscopic power generation material based on lithium chloride, ink and corn stalks that can be used for water collection in the air and humidity power generation and a preparation method thereof. Background technique [0002] With the rapid development of industry and the increase of population in the world, the shortage of water resources has become a global problem that needs to be solved urgently. According to the United Nations survey, 40% of the world's population is facing a shortage of fresh water resources. In order to solve the problem of water resources, researchers have developed a variety of water production technologies, such as seawater desalination, sewage purification and water harvesting from the air. Among these technologies, air water harvesting technology has gained a lot of at...
